pnpm [ -h | --help | -v | --version ]

Manage your dependencies:
    add                  Installs a package and any packages that it depends on. By default, any new package is installed as a prod dependency
    import               Generates a pnpm-lock.yaml from an npm package-lock.json (or npm-shrinkwrap.json) file
 i, install              Install all dependencies for a project
it, install-test         Runs a pnpm install followed immediately by a pnpm test
ln, link                 Connect the local project to another one
    prune                Removes extraneous packages
rb, rebuild              Rebuild a package
rm, remove               Removes packages from node_modules and from the project's package.json
    unlink               Unlinks a package. Like yarn unlink but pnpm re-installs the dependency after removing the external link
up, update               Updates packages to their latest version based on the specified range

Review your dependencies:
    audit                Checks for known security issues with the installed packages
    licenses             Check licenses in consumed packages
ls, list                 Print all the versions of packages that are installed, as well as their dependencies, in a tree-structure
    outdated             Check for outdated packages

Run your scripts:
    exec                 Executes a shell command in scope of a project
    run                  Runs a defined package script
    start                Runs an arbitrary command specified in the package's "start" property of its "scripts" object
 t, test                 Runs a package's "test" script, if one was provided

Other:
    cat-file             Prints the contents of a file based on the hash value stored in the index file
    cat-index            Prints the index file of a specific package from the store
    find-hash            Experimental! Lists the packages that include the file with the specified hash.
    pack                 Create a tarball from a package
    publish              Publishes a package to the registry
    root                 Prints the effective modules directory

Manage your store:
    store add            Adds new packages to the pnpm store directly. Does not modify any projects or files outside the store
    store path           Prints the path to the active store directory
    store prune          Removes unreferenced (extraneous, orphan) packages from the store
    store status         Checks for modified packages in the store

Options:
-r, --recursive          Run the command for each project in the workspace.

Reproduction steps

👋 Hey @Sabine-Tieland,

Thank you for reporting this!

I'm facing some challenges reproducing this issue on my end.

Could you please share your full shopify theme dev --verbose output? That would really help us understand the sequence of requests involved (with the number of reports we’ve seen, it seems this may be related to the region where the command is executed—but we’ll need the --verbose output to confirm that hypothesis and fix it)

Thank you!

This exact same issue has happened to me this afternoon, exactly as described above. If I preview the editor [e], all is fine, if i preview the theme (t) as above.

Verbose output if any help:

Also experiencing this issue. Always with github sourced themes but that might be because I'm not using any themes not sourced through github. Anyways the solution to when it happens is deleting the github sourced theme in Shopify and then adding it again. Then, you just specify the re-uploaded theme's id by running:

shopify theme dev --store <id>

However, it's pretty anoying.

Sep 25 '25 11:09 wake-digital

👋 Hey @SteveMcC71,

Thanks so much for sharing your context! I took a look at the --verbose output you posted, but it doesn't seem to include the Theme ID mismatch error just yet.

Could you grab a copy of the output where that error appears and share it here? That would help a ton.

--

👋 Hey @wake-digital,

If you could share your output as well, that would be very helpful.

--

It looks like the root cause of this issue might be region-specific. Your --verbose outputs are essential for us to make sure the fix actually addresses the problem you’re encountering.

Thank you, everyone, for reporting.

Sep 29 '25 08:09 karreiro

@karreiro sure. The reproducibility just isn't quite reliable. I'll try to remember to grab it once it happens though. Btw my guess is that it's related to some cache causing trouble - that seems to be a common trend with most of the Shopify bugs I've come across.

Sep 29 '25 08:09 wake-digital

@karreiro are you available right now? I've gotten the thing to happen again, but the verbose logs literally exceed my terminal's scrollback limit, so I doubt I'd be able to copy it all here.

Anyways here's a bit towards the end:

Oct 01 '25 12:10 wake-digital

Oh I see. The "got" id seems to refer to the theme which is being used for dev instead of the one that was specified ("expected") - that seems to make more sense.

Oct 01 '25 12:10 wake-digital

So yeah - TLDR:

"expected" in the error code refers to the implicit dev theme or the explicit theme id from the --theme flag
"got" refers to the main theme id.

Oct 01 '25 12:10 wake-digital

Damn so yeah the only way to run dev on the store is to run it on the main theme :d Hilarious. Doesn't seem to be a cli issue directly though, because I can run it normally on a different store right now. So it has to have something to do with the store data.

Oct 01 '25 12:10 wake-digital

Also, what I said before about removing and re-importing the theme being a solution was a hoax.

Oct 01 '25 12:10 wake-digital

I have been seeing this for around a month also. The latest version of the CLI seems significantly worse and I can no longer use the 127.0.0.1:9292 URL at all.

I am able to preview if I use the generated theme preview URL at the sites domain hostname, however this breaks hot reloading entirely.

Oct 07 '25 14:10 YourWishes

Additional context: I have the theme ID missmatch issue happening on store X. I also work on store Y which is basically a mirror with products which have the same handles - just on a different Shopify entity to have two separate stores with two separate default currencies. The thing is, when I use the CLI for shopify theme dev --store=<Y>.myshopify.com on the Y store with the Y store theme, it seems to load the store context for the X store even though it should be getting it for Y (Similar to what @YourWishes has descibed, this only happens on local-host. The shopify hosted preview is fine). I tired deleting some files from my machine which could contain some cache as well as signing off from the CLI and signing back in, but nothing helped.

All of this is convincing me strongly that this is some caching issue happening on Shopify's backend (therefore not part of this project, I'd assume)

Oct 08 '25 14:10 wake-digital

Hi everyone, thank you so much for these detailed reports. Can you please let us know starting from today if you experience this again. We have attempted to mitigate the issue on our backend. If you experience this again I would love to grab logs around the error (although I do understand it's difficult as it's intermittent).

Oct 20 '25 19:10 EvilGenius13

@EvilGenius13 well I mean it didn't happen again... 'cause it still doesn't work just as it hasn't a month ago :d

Oct 22 '25 13:10 wake-digital

I'm free to give you any logs or whatever you request

Oct 22 '25 13:10 wake-digital

@wake-digital sorry to hear it's still happening. Thank you for helping out! I was looking into this yesterday and I believe something might be happening with the CLI session during a refresh, however I can't confirm it because the logs we have are partial. I know these logs can be massive but somewhere in there will show the last few requests before it falls apart with the id mismatch.

If you could get a full .txt log that I could comb through it would really help. I believe you should be able to drag and drop it into a reply here. If not, you can email it to me at [email protected] I super appreciate the support here.

Oct 22 '25 13:10 EvilGenius13

@EvilGenius13 okay so just shopify theme dev with verbose, right

Oct 22 '25 14:10 wake-digital

@wake-digital Yup!

Oct 22 '25 14:10 EvilGenius13

@EvilGenius13

LOG.md

Please just assure me there's no sensitive information in the logs lol

Oct 23 '25 07:10 wake-digital

Thank you! You are good. I'm going to dig in this morning.

Oct 23 '25 13:10 EvilGenius13

Hey @wake-digital, I've started to dig a bit further and if you can help that would be awesome.

There are two different things I notice.

Your myshopify.com domain has a force redirect to another domain.
On your failed request we see Rendering https://yourshop.myshopify.com/?_fd=0&pb=0 (with config/markets.json)... <---- this config/markets.json might be pointing us somewhere else.

I'd like to try separating these to see if we can pinpoint the problem.

Could you try making a basic theme or use the default theme from horizon and run theme dev verbose with it on your shop.
- If you don't experience a problem then it might have to do with the markets file and how we point to them.
- If you still have the problem, then it might be the fact we have that forced redirect.

Please let me know if you have any questions!

Oct 23 '25 20:10 EvilGenius13

@EvilGenius13

I tried some Dawn we've had on the store and that got the same error, so how do I figure out if it's because of the forced redirect, and why isn't forced redirect an issue on other stores?

Btw did you consider the fact that it works when I explicitly run it on the live theme id?

Oct 24 '25 04:10 wake-digital

@EvilGenius13 hmmm I just cloned the Horizon theme you referenced just to make sure... I didn't put it into the store directly but just ran shopify theme dev on it locally on that store and it seems to want to work (there are just some errors in the theme for some reason, but the CLI doesn't fail)

Oct 24 '25 04:10 wake-digital

Thanks @wake-digital

Btw did you consider the fact that it works when I explicitly run it on the live theme id?

No I didn't and I'll keep that in mind, I just can't think of why it would work but others wont

Thanks for trying it with Horizon. The first run will sometimes have errors but if you kill the terminal and do it again it should properly kick up a full dev session for you.

so how do I figure out if it's because of the forced redirect, and why isn't forced redirect an issue on other stores?

This is a great question! We can narrow it down further.

Do you work on any other stores that do a forced redirect, or just this one?
- If you do have another store with one, do you also work with the markets.json file in it? The TLDR for now is that when we run theme dev we create a session on the your-store.myshopify.com domain. If there is some kind of forced redirect to another domain for whatever reason that might be, the session won't be attached to that domain and I believe that's why you get the mismatched ID. I've already started talking to other teams about this.

For now the important part is digging down to figure out if it's from the forced redirect, the markets setup.

@EvilGenius13 hey don't you mind phrasing what I'm supposed to do more simply?

Hey @wake-digital for sure!

** Step 1: Testing on a store with a redirect:**

Using the store that the domain redirect (intercut-eur.myshopify.com), try a theme that does not include markets and run theme dev (you may need to run it twice because sometimes on the first run it has file upload errors). Can you update the theme, click around and have a session that runs at least 10 minutes without getting the Theme ID mismatch?

If you had a mismatch error - This is likely something weird with the domain configuration and we might need to figure out why it's behaving oddly. If you didn't have a mismatch error - I think it has to do with markets and how we send details along with them in sessions.

We were able to replicate the issue. This does have to do with having custom domains and markets enabled. We have a temporary workaround assuming your setup is similar to mine. If this does not fix the problem please let us know as there may be multiple ways to cause the error.

Go into your store admin page, click settings and then click on domains.

It's likely you have a setup that looks like this:

mystore.myshopify.com PRIMARY
|
|-> shop.mydomain.com

ca.mydomain.com
us.mydomain.com

The important part is this: If your primary domain is your myshopify.com domain, when you try developing in the CLI it will redirect to your custom domain and that is where it fails. The session won't cross domains.

However - if you make your primary domain the custom domain that matches with your markets, it will work. So making the domains page look like this instead:

shop.mydomain.com PRIMARY
|
|-> mystore.myshopify.com

ca.mydomain.com
us.mydomain.com

Hi @EvilGenius13,

I'm experiencing exactly the same issue as @wake-digital and I'm really looking forward to solving it as soon as possible.

Following up on your suggestion, I'm not really sure what exactly I should change when it comes to the domains. In my case, the domains settings tab looks like this:

www.customdomain.nl PRIMARY | |-> customdomain.nl shopify-domain.myshopify.com

So, in this case, www.customdomain.nl is our Primary domain, then customdomain.nl points to the www.customdomain.nl, and when I inspect the details about the Shopify domain (shopify-domain.myshopify.com), I see it says: "Market domain for Germany", which is a different market from our main one since we sell primarily in the Netherlands.

Also, I noticed that when I delete the markets.json file from the theme files and I run shopify theme dev --verbose, I can see that the issue is still there. But one more thing to note is that now, it seems we are selling in two markets: Germany and the Netherlands, but my markets.json file contains only this {"markets":{}}. It's basically empty, I'm not sure if this is supposed to be like that or not, but it is now.

So, having said all this, what do you suggest I do now to try to resolve this issue and how should I proceed?

Please, let me know if you need anything else from me.
