Version

8.1.0

Steps to Reproduce

After upgrading to sentry_flutter 8.1.0 from sentry_flutter 7.20.2, I'm encountering these warnings when running flutter packages pub run sentry_dart_plugin:

...

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

      - warning: could not determine a source map reference (Could not auto-detect referenced sourcemap for ~/lib/core/models/agendamento/agendamento.freezed.dart)

      - warning: could not determine a source map reference (Could not auto-detect referenced sourcemap for ~/lib/core/models/agendamento/agendamento_lowlevel.freezed.dart)

...

Additionally, it seems that exceptions are not being captured correctly, as the stack traces are incomplete:

main.dart:

Future<void> main() async {
  runZonedGuarded(
    () async {

      await SentryFlutter.init(
        (options) {
          options.dsn = dsn;
          options.tracesSampleRate = 1.0;
          options.environment = environment;
          options.attachScreenshot = true;
          options.release = release;
        },
      );

      runApp(
        ProviderScope(
          child: SentryScreenshotWidget(
            child: const MyApp(),
          ),
        ),
      );
    },
    (error, stack) async {
      await Sentry.captureException(error, stackTrace: stack);
    },
  );
}

pubspec.yaml:

...

sentry:
  upload_debug_symbols: true
  upload_source_maps: true
  upload_sources: true
  project: 'frontend'
  org: 'org'
  auth_token: 'token'

I tested downgrading sentry_dart_plugin to version 1.7.1 while keeping sentry_flutter 8.1.0, and now the warning 'could not determine a source map reference' is not appearing anymore, and the stack traces are complete now.

So, I think the problem lies with sentry_dart_plugin 2.0.0.

@denrase Can you please take a look

[kuhnroyal]

getsentry/sentry-dart-plugin#203 looks related
I am getting the same error for every source file though.

[denrase]

@buenaflor I checked with sentry-cli v2.31.0 and v2.32.0. Both do not work. Downgrading to v2.27.0 fixed the issue for me:

So the issue seems to be with sentry-cli, and not with the plugin itself.

As a workaround, users can stick with 1.7.1 or provide a path to a local sentry-cli binary with bin_path param, which is a new feature we have introduced in 2.0.0.

[kuhnroyal]

Would it make sense to add a feature to specify a custom CLI version instead of a path?

[buenaflor]

@kuhnroyal I think that might a good addition if we can easily do it
