HTTP Exception with status code 500 causing Fatal Exception

🐛 Bug Report

Looking for some help trouble shooting this.

The following error is being reported in Crashlytics.

Fatal Exception: FlutterError
HttpException: Invalid statusCode: 500, uri = http://10.37.1.72:8735/api/v1/images/9539e80-653-4e5e-80cc-0f43db5d3c22. Error thrown Instance of 'ErrorDescription'.

flutter_error_reason
thrown HttpException: Invalid statusCode: 500, uri = http://10.37.1.72:8735/api/v1/images/9e539e80-6f53-4e5e-80cc-0f43db5d3c22. Error thrown Instance of 'ErrorDescription'.

Q: What does it mean when it says "Error thrown Instance of 'ErrorDescription'"?

Unfortunately, I do not have access to this site where the issue is happening.

Here is the Stack Trace

Fatal Exception: FlutterError
0 ??? 0x0 FirebaseCrashlytics.recordError+ 119 (firebase_crashlytics. dart:119)
1 ??? 0x0 FirebaseCrashlytics.recordFlutterError+ 145 (firebase_crashlytics.dart:145)
2 ??? 0x0 FirebaseCrashlytics.recordFlutterFatalError + 158 (firebase_crashlytics.dart:158)
3 ??? 0x0 FlutterError. reportError + 1184 (assertions.dart: 1184)
4 ??? 0x0 ImageStreamCompleter.reportError + 733 (image_stream.dart:733)
5 ??? 0x0 new MultiImageStreamCompleter. + 32 (multi_image_stream_completer.dart:32)
6 ??? 0x0 -AsyncStarStreamController.addError(dart:async)
7 ??? 0x0 new MultiImageStreamCompleter. + 25 (multi_image_stream_completer. dart:25)

It seems like the error is being raised here (in multi_image_stream_controller.dart line 32).

onError: (dynamic error, StackTrace stack) {
reportError(
context: ErrorDescription('resolving an image codec'),
exception: error,
stack: stack,
informationCollector: informationCollector,
silent: true,
);

Apparently, there are no listeners in the ImageStreamCompleter reportError handler so it calling the FlutterError.reportError (in assertions.dart line 1184)

if (!handled) {
FlutterError.reportError(_currentError!);
}

Where it fails the assertion verifying the passed arguments?

static void reportError(FlutterErrorDetails details) {
assert(details != null);
assert(details.exception != null);
onError?.call(details);
}

Never mind. It is not failing on the assertion, it looks like it is calling the Flutter error handler and Crashlytics is reporting a fatal error.

It seems like I need to update the handler to check the "silent" property and ignore these when set, otherwise forward to the Crashlytics error handler.
