Caught exceptions being treated as uncaught exceptions in some IDEs (?)

[vermefr]

Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Steps to reproduce

I've got an issue with flutter beta "3.12.0".
I was on "3.11.0-0.1.pre" just before, without any trouble.

With beta "3.12.0", an uncaught exception is reported by VS code: "Exception has occurred.
SocketException (SocketException: Failed host lookup: 'www.mycadwork.com' (OS Error: Host not found.
, errno = 11001))"

Expected results

Access to my webpage, without any uncaught exception under VS code.

Actual results

I get an uncaught exception: "Exception has occurred.
SocketException (SocketException: Failed host lookup: 'www.mycadwork.com' (OS Error: Host not found.
, errno = 11001))"

IMPORTANT NOTES:

1. The command "flutter run" does not report any exception !
   The exception I get is reported by VS code only.
   I didn't update any VS code extension when switching to beta v3.12.0.
   And If I roll back to flutter beta "3.11.0-0.1.pre", I get no more exception.

2. If I uncheck "Uncaught Exceptions" in VS code, everything works fine (i.e. I get a correct response from my server).

3. My VS code installation info:
   Version: 1.79.2 (user setup)

}

class _MyAppState extends State<MyApp> {
  @override
  void initState() {
    super.initState();

    () async {
      try {
        var response = await http.get(Uri.parse('https://www.mycadwork.com'));
        print(response.statusCode);
      } catch (e) {
        print(e.toString());
      }
    }();
  }

  @override
  Widget build(BuildContext context) {
    return const Placeholder();
  }
}

Thanks for the report @vermefr
Can you take a look at this comment and see if it helps in your case ?

[vermefr]

@darshankawar No it doesn't help, because I am in the case where I check "Uncaught Exceptions", not "All Exceptions"

[darshankawar]

Thanks for the update @vermefr
Does the same error occur on latest master as well ?

flutter channel master
flutter upgrade

Yes, same problem with Channel master, 3.12.0-7.0.pre.44.

Hi @vermefr
I can reproduce this issue on VSCode but when I change website to flutter.dev or any other one, the issue doesn't appear (it returns code 200).
Is that your website? Is there any possibility that there is an issue with it?

[vermefr]

I have three servers hosted by different companies. All 3 cause this error.
May be there is something wrong with the initial connection timeout. Is it managed differently after version 3.11.0-0.1.pre - beta ?

[P-Jay357]

Me and my team have been experiencing sporadic failed host lookup error responses. Most of the time the HTTP calls will return OK, but sometimes we get this error back. This occurs with our own endpoint calls, but also when calling other external API's, so it seems to be a wider issue.

[darshankawar]

Thanks for the update. Based on our findings, keeping this issue open for team's attention and tracking.

[darshankawar]

/cc @DanTup for thoughts.

[P-Jay357]

I will note though that we have been having the sporadic failed host lookup issue for a few months, so for us it wasn't introduced as part of 3.12.

[DanTup]

I don't seem to be able to reproduce the issue described here. I've tried with both stable and beta, but with "Uncaught Exceptions" ticked and "All Exceptions" unticked, the debugger does not break.

I do see an exception printed, but it's different to the one above Edit: That was because I was missing com.apple.security.network.client in macos/Runner/DebugProfile.entitlements. Once I added that, I don't get any exceptions at all (testing with 3.12.0-1.1.pre).

For those that are seeing this issue, can you confirm:

1. That when this occurs, the debugger is breaking and you're seeing the red exception popup in VS Code?
2. Whether you can reproduce this in a simple bin/foo.dart script that's run directly with Dart (eg. without Flutter)?

   Future<void> main() async {
     try {
       var response = await http.get(Uri.parse('https://www.mycadwork.com'));
       print('success: ${response.statusCode}');
     } catch (e) {
       print('fail: $e');
     }
   }

[DanTup]

Correction, I can reproduce this on Windows.

It seems like the exception is being treated as uncaught, even though it is caught. I don't know why this is, it might someone more familiar with the VM/debugger to look at this.

Here's a log of all the VM Service traffic:

log.txt

It was reproduced running the following Dart script (using the SDK from Flutter 3.12.0):

import 'package:http/http.dart' as http;

Future<void> main() async {
  try {
    var response = await http.get(Uri.parse('https://www.mycadwork.com'));
    print(response.statusCode);
  } catch (e) {
    print(e.toString());
  }
}

The log shows the debugger stop with a PauseException event at this location here:

https://github.com/dart-lang/sdk/blob/630482342f3022d2e53875e483e3acbcf9ed006d/sdk/lib/_internal/vm/bin/socket_patch.dart#L520

But the exception pause mode was set to unhandled:

{"jsonrpc":"2.0","id":"10","method":"setIsolatePauseMode","params":{"isolateId":"isolates/246517315303331","exceptionPauseMode":"Unhandled"}}

I wonder if it could be related to dart-lang/sdk#47985 ?

[GameTec-live]

i got the same issue!

[shymek]

I have the same issue. Only happens to me when I launch the app from VSCode. When I run it from the command line it works fine.

[darshankawar]

/cc @DanTup for thoughts on above comment.

[mattmyne]

Same issue running flutter_map package from vscode in Windows (windows-x64) debug mode.

Just created a new application using the "Flutter: New Project", Application (Empty), entered:
flutter pub add flutter_map
flutter pub add latlong2
and pasted the quickstart code from:
https://docs.fleaflet.dev/#demonstration

With only "uncaught exceptions" ticked I also get a SocketException "Failed host lookup: 'tile.openstreetmap.org'" "The requested name is valid, but no data of the requested type was found.", errno = 11004 in L520 of dart:io-patch\socket_patch.dart (same location as reported by @drocha87)

Also runs fine in both debug and run from flutter run command (and build). Unchecking both "All" and "Uncaught" breakpoints options in the debugger lets the program run without issue.

I'm using stable Flutter 3.13.0 (I've not tried on earlier versions)

[DanTup]

/cc @DanTup for thoughts on above comment.

I think there are a couple of different issues that might be described above. They look very similar, but have different causes. I suspect they are covered by:

1. Debugger pauses on handled exceptions in async* methods as if they are unhandled dart-lang/sdk#47985 - this is the VM incorrectly detecting whether an exception will be caught
2. "Failed host lookup" caught exception when using http.openUrl() dart-lang/sdk#52615 which was closed in favour of a proposal at Do not break on exceptions thrown in undebuggable code if caught in undebuggable code devtools#5883 - this proposes stopping the "All Exceptions" tickbox from causing the debugger to break inside "non debuggable" files (eg. something the user can select between their own code, packages, SDK libraries in VS Code)

The first one I think is absolutely a bug. The second one is probably just behaviour that is not ideal - many users debug with "All Exceptions" ticked in the VS Code debugger which causes the debugger to pause on exceptions even if they will be caught. This is by design, but I think generally users want "pause on exceptions even if they will be caught if they are in my code". The simplest workaround is to untick "All Exceptions" and only break on "Uncaught Exceptions" unless you are specifically trying to debug something related to a caught exception. Breaking only on "Uncaught Exceptions" is the default in VS Code, and the option I would recommend for general development.

[rdesimone]

After updating to Flutter 3.13 the issue started. Unticking Dart Exception Breakpoint -> Break on exception in Intellij solves the issue but it does not feel good somehow and it was not needed before...

Exactly same issue here.

[GameTec-live]

Why is this issue now in latest stable, how did it slip through from beta to stable??

[GameTec-live]

btw, 3.13.0

[arhamcode]

Same issue here, after update from 3.10.6 to 3.13.0

[GameTec-live]

Same issue here, after update from 3.10.6 to 3.13.0

yeah, this makes developing annoying, because every time you wanna debug something that makes a web request you cant debug it in vscode but gotta do flutter run...
Why isnt this somewhat higher proprity? :p

[DanTup]

you cant debug it in vscode but gotta do flutter run...

You should be able to run without debugging by using the Run options (instead of Debug) in VS Code (which should be the same as flutter run and should not pause on any exceptions, caught or uncaught):

You should also be able to untick both "All Exceptions" and "Uncaught Exceptions" on the sidebar and get similar behaviour.

However my understanding was that there are two issues here, and the issue with web requests only occurs if you have "All Exceptions" ticked on the debug sidebar (instead of just "Uncaught exceptions"). If that's not the case, I'd be interested in a small (but complete) repro I can use to test.

[tylandercasper]

Downgrading to flutter 3.10.6 resolves this issue.

[Ivan981508]

I am facing the same problem after upgrading to 3.13

[arhamcode]

i found this exception raised when we made request to website that doesn't ready for IPv6. For example :

• https://flutter.dev/ (is ready for IPv6)
• https://nytimes.com/ (not ready for IPv6) will throw SocketException

Related closed issue here #50868 and has been fixed on iOS, maybe, thats why it only appear on android.

[tylandercasper]

I'm getting this on Windows, so it's not just limited to android.

[jenpingus]

I am getting the same message after upgrading to 3.13

[Hixie]

Fundamentally this issue is not likely to make much progress where currently filed, since it is not one that any member of the Flutter team can fix directly, but is instead an issue in the underlying Dart VM. I am going to close it because we believe it is a duplicate of dart-lang/sdk#47985, which already tracks that particular bug.

For changes to the IDEs, I recommend filing a bug with the IDEs or the relevant plugins. For other changes to Dart's VM logic, I recommend filing bugs on the Dart SDK.

[DanTup]

I opened dart-lang/sdk#53334 specifically for this issue. It seems to be slightly different from dart-lang/sdk#47985 and seems newly-introduced in Dart 3.1.

[gselvatico]

Same issue after update to 3.13.0

[mike993]

same here too T.T

[medkira]

same issue here too , the thing is it work normal in a local server.
