Sourcemaps are uploaded but not used
Environment
Running a self-hosted version of Sentry. Deploying a static React app (Vite builder, Vercel for deployment)
"@sentry/tracing": "^7.114.0",
"@sentry/vite-plugin": "^2.22.6",
...
"vite": "^5.4.10"
vite.config.ts
defineConfig({
plugins: [sentryVitePlugin({
org: 'myproject',
project: 'internal',
telemetry: false,
sourcemaps: {
assets: './dist/**',
filesToDeleteAfterUpload: ['./**/*.js.map'],
},
release: {
name: process.env.PUB_RELEASE,
},
authToken: '...',
})],
build: { sourcemap: true }
}
- I've made sure the build is a
productionbuild. - The release has a defined name.
- I've made sure the files (both minified .js and .js,map) are uploaded by going to the admin panel.
- The source maps work in the browser.5. I have completed this checklist to no avail https://docs.sentry.io/platforms/javascript/sourcemaps/troubleshooting_js
Steps to Reproduce
After a deployment, if the sourcemaps are exposed on the server, Sentry picks them up and uses them in Issues. But once I use filesToDeleteAfterUpload to remove them, it stops resolving even though they are successfully uploaded.
Expected Result
Sourcemaps are used to resolve stack traces in the Issues tab.
Actual Result
Issues tab still shows the minified version.
Can you please help me debug this? I've sat for several days on this and can't sort it out.
Hi, can you check the logs of your self-hosted symbolicator service when you set filesToDeleteAfterUpload? Thanks!
Hey. The logs look like this

I didn't see any error messages or warnings.
I'm experiencing what appears likely to be the same issue: self-hosted Sentry (24.12.1), @sentry/vite-plugin (2.23.0) that says the source maps are uploaded successfully, Sentry shows uploaded source maps in the project settings (with the upload ID and debug IDs reported by the Vite plugin, and that correspond to the debug IDs that got baked into the source files), but it isn't making connections when the issues are reported by the Sentry JS plugin (7.120.3).
I haven't dug in to see exactly how they're supposed to be correlated on the server side, so a few observations of things that don't quite line up:
-
The web interface's "Source Maps Loaded" section seems to imply that the JavaScript file hasn't been identified: (index-DffsctBF.js is our main application's JS, there is a separate chunk that is split out because it is rarely needed)
If I click "View", I get a debug ID that matches what has been uploaded:
But clicking "Open in Settings" sends me to the "Debug Files" part of the project's settings (where no source maps exist), not the "Source Maps" section (which contains the uploaded source maps). I assume this is an errant link in the web interface, rather than an indication that source maps should be processed into debug files somehow, but I'll highlight it just in case. The relevant source map upload:
As you can see, the matching debug ID is shown on both the Sentry issue and the source map upload, so I would have expected this to be sufficient. However, the artifact file names do not match what Vite generated (
index-DffsctBF.js), though it does seem to at least have had that reference, as the minified version is listed with "Sourcemap Reference: index-DffsctBF.js.map". My best guess is that the mismatched names are the cause of Sentry not loading the source maps. -
With debug enabled, these are the logs from sentry-vite-plugin when I delete the source files on Sentry and re-build (notably the source files seem to remain somehow on the server, though I had deleted them in the project's settings page - I don't think it's related to this problem, but we also build and upload a separate copy on an ARM platform - Sentry groups these together, so they may be the same output):

That's my best guess as to the cause of the issue, but again, I don't know how source maps are identified on the server side, so it's possible they're irrelevant.
You may have noticed our source maps are fairly large, so even though the files are accessible to Sentry, it doesn't seem to pull them down, so I can't quite confirm the same symptoms that @poskadesign is seeing, though the issue feels very similar. (I believe that change in Sentry happened years ago, which is why we push source maps directly.)
Despite commenting on this issue today, this is not necessarily a particularly new issue for us: I don't know if we've ever had working source maps since we switched to Vite several months ago, I just got time this week to investigate, update everything to the latest versions, and try to resolve the problem. (I also don't know where the issue lies: it could be the plugin not uploading correctly, or it could be the server not correlating source maps and debug IDs.)
@aschmitz you have a dist set on the upload. Can you confirm that your Sentry.init() has the same exact dist? Also, in the event, there should be a button "unminify code" - what does it say when you click it?
Also please share screenshots and event payloads of the events if you're able to!
Regarding the dist value, that's a good shout: we aren't setting it in Sentry.init() (though we are setting the release). We did have the same symptoms with the same versions of the software before setting dist (I was setting it just in case the Vite bundling wasn't deterministic, to try to differentiate the compiled files. However, the Sentry plugin did say that the files already existed on the server regardless - and the Source Maps page grouped them both together with the same files - so I suspect that may not have been the issue. (I will probably revert back to removing dist entirely, as it's an unnecessary complication.)
On the Sentry page for the event, I'm not seeing an "unminify code" button, but there is a "Minified" checkbox under the three-dot menu on the Stack Trace section. Unfortunately, it is greyed out, and has a tooltip saying "Minified version not available".
I'm also not sure how to get the full event payload, but I pulled the JSON from the three-dot menu next to Event ID, lightly redacted it, and that's this: event_redacted.json . I have a lightly-redacted version of the Sentry issue screenshot, as well: Issue Page. The "Full Event Details" page looks to be nearly identical, but if there's something else there you'd like a screenshot of, let me know.
@aschmitz payload looks good. Your guess that the filenames are different is unrelated. Can you please check the logs of your symbolicator service? Thanks!
Hey @lforst. When you say simbolicator, do you mean sentry-self-hosted-symbolicator-cleanup-1? It does not show any errors at all, only this

As an update, I recently upgraded to Sentry 25 and still have the same issues.
- The source maps are automatically uploaded (as signaled by the Sentry Vite plugin).
- I can view the minified js and map files in the project releases
- In the issue view I can confirm that the file names match but for some reason Sentry just says "unreferenced"
I've been trying a lot of different variations of my config (using different paths for assets, removing the filesToDeleteAfterUpload, using different sourcemap types). There are no errors or warnings on deployment.
I even deployed the source maps publicly, Chrome picks them up no problem:
@poskadesign No I mean the symbolicator service. The symbolicator service not running may be the reason sourcemaps are not working for you.
