"Could not find the task..." error when using a .code-workspace file.

[JaneySprings]

Hello. I created a debugger for .NET apps. It's requires a preLaunchTask: "dotnet-meteor: Build" in the launch.json. This task is always provided by vscode.TaskProvider (TaskScope.Workspace):
https://github.com/JaneySprings/DotNet.Meteor/blob/main/src/VSCode.Extension/tasks/build.ts

If you are not using a code-workspace file, then you can create a launch.json file and run the debug.
But if you use the code-worksapce file, then when you run the debug you will get the error:

in the debug, I see that VSCode requests a task and receives a response, but the error still occurs:

Does this issue occur when all extensions are disabled?: Yes

I cannot reproduce in insider's - it's possible this was fixed in the past month. Could you pls verify if it's working for you?

Hi! I tried on сode-Insiders version, but nothing changes :(
I created a simple extension where you can reproduce this bug:
https://github.com/JaneySprings/VSCodeLaunchBug

It also contains two folders:
https://github.com/JaneySprings/VSCodeLaunchBug/tree/main/SimpleFolder - folder with launch.json
https://github.com/JaneySprings/VSCodeLaunchBug/tree/main/SimpleFolderWorkspace - folder with code-workspace

In your repro, where is Test: task defined? I think that's the issue.

[meganrogge]

See it is working here when the task has been defined.

workspace.mov

[meganrogge]

I get the same error when launching from the simple folder for that reason.

[JaneySprings]

@meganrogge it's work when task defined. But why is it not necessary to create tasks.json for a simple folder? Is this definitely not a bug?

[meganrogge]

The task has to be defined somewhere - whether in the workspace file or the tasks.json for us to know what to run.
