VSCode Debug Redash Flask App

README.md

This is for launching and debugging Redash Flask app in VSCode.

We couldn't use the default Flask runner, because Redash implemented its own cli command manager.

We must use "program": "${workspaceFolder}/manage.py" instead of "module": "manage" because the relative path will cause some path issue, and result in template file not found errors.
