Could you share the debug launch configuration with us?

@alexr00 the error message originates from the prelaunchTask

[alexr00]

@KingJch can you share your tasks.json file?

Thank you! @KingJch if you run yarn run web:watch from the VS Code integrated terminal manually does it work in your multi-root setup?

[KingJch]

@alexr00 it work

[alexr00]

I'm not able to reproduce the issue. My steps:

1. Make a multiroot workspace
2. Make sure one of the folders in the workspace has a launch.json file with a launch config with a prelaunch yarn/npm task.
3. Select that launch config and debug.

@KingJch can you provide a few more details please:

• What operating system are you using?
• How did you launch VS Code?
