Python Debugging failing #16757
Description
- Add breakpoint to a python test case or (in any python file)
- Select debug test
- Debugging fails with the following error
- Tests run successfully without debugging
Debugging was working without any issues. Stopped working all of a sudden. The only thing that I had done was a Git merge. But it cannot be the issue as I tried to debug a completely different plain hello world Python file with the same issue. I did not add any extensions or in any way change the setup of VS Code.
The error in the Python Test Log Output window is:
Error: TypeError: Cannot read property 'testsuites' of null
The traceback in the Debug Console is:
