Outcome When Attempting Debugging Steps:
Did running it from the command line work? Short answer, practically yes.
- I tried to run this on the command line and got stuck:
/Users/andres/workspace/cactus-ins-dj/.venv/bin/python /Users/andres/.cursor/extensions/ms-python.pylint-2025.2.0/bundled/tool/lsp_server.py - Also tried this and also got stuck:
/Users/andres/workspace/cactus-ins-dj/.venv/bin/python -m pylint --reports=n --output-format=json --clear-cache-post-run=y --from-stdin /Users/andres/workspace/cactus-ins-dj/insurance/commands/policies/create_policy.py - Finally I simplified the last command to this and it worked:
/Users/andres/workspace/cactus-ins-dj/.venv/bin/python -m pylint /Users/andres/workspace/cactus-ins-dj/insurance/commands/policies/create_policy.py
