firebase deploy --only functions

[Molnfront]

I tried to only depoy the functions and got this:

Error: Could not detect language for functions at /Users/.../firebase/functions

Then I tried:

firebase init functions

and got:

=== Deploying to 'noshit'...

[Molnfront]

Hm, I found out that init created a new functions folder in the root with the necesary package.json and node_modules folder. So I copied those except the index.js to the /firebase/functions folder.

Then tried to deploy again.

Got error agsain because of missing packages.

Had to install the following packages:

firebase-function-tools

@firebase/[email protected]

nodemailer

mkdirp-promise

child-process-promise

Now I could deploy.

11 warning about code in the function:

[Molnfront]

Region is hard coded in some of the functions..

[Molnfront]

Are those functions tested?

[Molnfront]

Fixed the second warning in onUpdate.f.js:

Changed map(() => {}) to map(() => ())

With () - implicit return takes place.

[Molnfront]

Hm, warnings and the failed to create does not seem to be related. for example auth-onCreate has no warnings but fails to deploy.

[Molnfront]

I have 45 of these in my firebase-debug.log: failed on loading user code. This is likely due to a bug in the user code. Error message: Error: please examine your function logs to see the error cause:

Checked the logs at: console.cloud.google.com/logs

severity: "ERROR" textPayload: "Function cannot be initialized. Error: function terminated. Recommended action: inspect logs for termination reason. Additional troubleshooting documentation can be found at https://cloud.google.com/functions/docs/troubleshooting#logging " timestamp: "2022-03-25T11:52:20.862903625Z"

I could not find the termination reason in the vast amount of errors.

[Molnfront]

The issue must be with the hard coded regions. You can not change a region for a project after it's created. So I am trying to change region to where my project is deployed.

[Molnfront]

Hm, it still deploys in us-central even when I have changed the hardcoded values with my own multi eu3 region.

[TarikHuber]

Are the database, strage, hostin and auth services enabled in your project?

[Molnfront]

yes, only. functions that i haven't tried before. But they are getting deployd to the wrong regions

[Molnfront]

functions: Finished running predeploy script. i functions: ensuring required API cloudfunctions.googleapis.com is enabled... i functions: ensuring required API cloudbuild.googleapis.com is enabled... ✔ functions: required API cloudbuild.googleapis.com is enabled ✔ functions: required API cloudfunctions.googleapis.com is enabled i functions: preparing firebase/functions directory for uploading... i functions: packaged firebase/functions (53.38 KB) for uploading ✔ functions: firebase/functions folder uploaded successfully

[Molnfront]

functions: failed to create function projects/test/locations/eur3/functions/db-adminsOnWrite

[Molnfront]

and the region that the project is set to seems not working

[Molnfront]

regions seems a bit random?

[Molnfront]

is there more hidden regions in the code? this is a real mess.. :-)

Why are the functions by default deployd to us-central1 and europe-west1?

[Molnfront]

found some edge cases:

Here's a mapping of the closest functions-supported regions for Cloud Firestore and Cloud Storage, for cases where the same region is not supported:

eur3 or europe-west (multi-region)	europe-west1

Important: If you are using HTTP functions to serve dynamic content for Firebase Hosting, you must use us-central1.

[Molnfront]

Ok, I will try to add this to all the functions:

exports.myStorageFunction = functions .region('europe-west1') .storage .object() .onFinalize((object) => { // ... });

[TarikHuber]

You can also remove all regions.

Tried a complete deploy.

But I can't find any functions in the console..

[TarikHuber]

You can sheck what projects you have in in your firebase.src file. Also update the firebase rules to version 2.

[Molnfront]

Yes, updated firebase rules to v2. Still got invalid functions names:

i cloud.firestore: checking firebase/firestore.rules for compilation errors... ⚠ [W] 14:14 - Invalid function name: exists. ⚠ [W] 14:63 - Invalid variable name: request. ⚠ [W] 19:15 - Invalid function name: get. ⚠ [W] 19:66 - Invalid variable name: request. ⚠ [W] 23:14 - Unused function: isGranted. ⚠ [W] 29:14 - Unused function: isOwner. ⚠ [W] 30:14 - Invalid variable name: request.

[TarikHuber]

Those look like error messages for code inside the function. Did you change any code or is it from the template?

[Molnfront]

I only added rules_version = "2"; to the firestore.rules file.

No changes other than that and yes it's from the template.

No functions is deployd..

[cwmat]

If helpful, I had the same issue you described RE "Could not detect language" and I also attempted firebase init functions which yielded the same deploy error.

After sniffing the firebase logs via the console looked like I was missing some npm packages.

I also noticed that the init call from before overwrote my package.json (or maybe I had done that manually when in a frenzy, I don't recall) for the functions and was using node 16 instead of node 14.

May not be the same issue you are having but, basically I just:

• deleted node_modules, and then overwrote the package.json with a fresh version copied from npx create-react-app my-app --template rmw
• npm install
• firebase deploy --only functions

and it worked. I had also removed the hard coded regions.

Here is the fresh package.json I used (valid at the time of writing this): https://gist.github.com/cwmat/b6333c5cc485346ca11693b64b439fdf

[TarikHuber]

@cwmat thx for pointing that out. Yes the only way to get the latest function updates is to copy them from s fresh package. I'm thinking if maybe firebase extensions would be useful but in the end the flexibility is my main goal with this project to do with it after the template what you want.
