[buenaflor]

hey, could you try out the plugin version 2.1.0? We have found an issue with source map uploads starting from plugin version 2.2.0

[fryette]

Looks like issue still exists

[buenaflor]

@fryette can you try the latest version 2 4.1, we released a fix that might solve this for you

[fryette]

@buenaflor Unfortunately same issue in 2.4.1

[buenaflor]

just to be sure, are your stacktraces still minified?

[fryette]

I'm sorry, probably I mislead you a bit.

My issue was that tool do not upload all sources to the Sentry, obfuscated or not obfuscated(it's iOS and Android related).

I found that issue where you suggested to downgrade to 2.1.0. Once I did it

1. All sources finally uploaded to Sentry(self hosted in my case)
2. All Sentry issues unobfuscated and looks as it should be

For versions higher than 2.1.0 I have an issue that

1. Source code not fully uploaded(actually just few files from 2K+ in compare with 2.1.0 upload logs)
2. Stacktraces not fully shown

[denrase]

@fryette Hey! We recently released 2.4.1, which should address issues with source context.

[otopba]

@denrase Same problem with 2.4.1

[denrase]

@otopba Could you check if everything works as expected on sentry.io? So is source context present in your issues where enabled with 2.4.1? I got the same warnings when running the plugin, but did have correct source context, so my suspicion is that these warnings are false negatives.

[otopba]

@denrase Hmm, interesting. Yes, at Sentry.io, everything is OK; I can see mappings and stack traces.

[denrase]

Ok, then we need to figure out why we report this warning when everything is on order. Thx for checking.

[buenaflor]

might be related https://github.com/getsentry/sentry-dart-plugin/issues/203

[alexobviously]

We are also experiencing this issue. We're on 2.4.1, still getting could not determine a source map reference warnings for every file, and stack traces and issue titles are all still minified.

[buenaflor]

@alexobviously hi do you have more info? how does your release/dist setup look like. it's important that the plugin uses the same release as the event you send so we can associate the sourcemap with the release/dist

[fryette]

I can confirm that it's still dont work with latest version.

[jonasbark]

Also confirmed here.

To reproduce:

1. create a new Flutter Web project
2. add sentry_dart_plugin: 2.4.1 to dev_dependencies
3. add to pubspec.yaml:

sentry:
  upload_debug_symbols: true
  upload_source_maps: true
  upload_sources: true
  ignore_missing: true
  project: test
  org: ...
  auth_token: ...
  wait_for_processing: true
  log_level: error
  commits: auto

4. build with flutter build web --release --source-maps
5. get the error:

Source Map Upload Report
  Scripts
    ~/lib/main.dart (no sourcemap found)
      - warning: could not determine a source map reference (Could not auto-detect referenced sourcemap for ~/lib/main.dart)

So frustrating :(

Also happens when run manually:

.dart_tool/pub/bin/sentry_dart_plugin/sentry-cli --url ... --auth-token ... --log-level error releases --org fieldbots --project app files [email protected]+1 upload-sourcemaps lib --ext dart --dist 1 --url-prefix ~/lib/ --wait

Forgot to add: Issues are still obfuscated. Using non-self hosted sentry.

[buenaflor]

The warnings can be safely ignored which I suspect are just false positives, what's important is that the source maps are uploaded.

@jonasbark how does your Sentry init look like?

I just tried it out locally on a new project which works

[jonasbark]

Thanks, I had another look and it works now after adjusting options.release = '1.0.0+3' to options.release = '[email protected]+3'

Sorry for the wrong alarm

[buenaflor]

Generally release and dist has to match with the release created by the plugin.

Soon we will implement associating source maps with debug ids which will completely make the release/dist association obsolete and is more robust https://github.com/getsentry/sentry-dart-plugin/issues/314

[jonasbark]

FWIW, the same exact procedure does not work on our self-hosted sentry instance. I updated it the sentry instance to 25.4.0.

Hosted:

Self-Hosted:

Keeping my hopes up with the debug IDs.

[buenaflor]

@jonasbark can you confirm that the sourcemaps were uploaded to the self hosted instance? they should be under your project > settings > source maps

[jonasbark]

Yes, they are, and it looks identical as well.

Hosted:

Self-Hosted:

All I did was adjusting the auth_token, url and project in pubspec.yaml and the dsn accordingly in the SentryFlutter.init part

[buenaflor]

It correctly identified to which release it was associated with at least. I suppose your events also contain the correct release?

Is your symbolication working for other platforms?

[jonasbark]

Yes, I hardcoded the release and dist parameters just to be sure. Also yes, symbolication generally works on e.g. iOS.

[zambetpentru]

Hi @buenaflor,

I am getting the same issue on Web with lack of recognition of the source maps:

With Sentry_dart_plugin 2.4.1 I was getting the 'could not determine a sourcemap reference' errors like the above screenshots. These disappeared when I downgraded to 2.1.0

I still get this error:

I can see the sourcemaps were uploaded, what can I do to try and narrow down the issue (it used to work).

[buenaflor]

@zambetpentru can you share how you set releases in the SentryFlutter SDK as well as your dart plugin config

[buenaflor]

as a general update, I'm working on the dart plugin v3 which includes debug id support which makes symbolication of web stacktraces much more reliable than the current implementation

[zambetpentru]

Hi,

in pubspec.yaml

name: project_name

version: 1.0.0+1

sentry: upload_debug_symbols: true upload_source_maps: true upload_sources: true project: aNameThatIsNotTheFlutterProjectNameAbove org: x auth_token: x

command: dart run sentry_dart_plugin

Is there any other information you need? Flutter 3.27.4 (last version that supports the HTML Renderer)

[buenaflor]

do you set the release in SentryFlutter.init as well?

[buenaflor]

hey we've recently released Sentry Flutter 9.1.0 and the Sentry Dart Plugin 3.0.0 which enhances the symbolication process, can you try it out and see if it improves it
