Reload on file change detected return exception SystemExit #2195

Closed sharky98 closed 3 years ago

sharky98 commented 3 years ago

Hello, I am using a kind of complex grouping of modules around Flask. Lately it started triggering an exception when doing the reload. I am using VS Code 1.55.2. I don't remember having made a major upgrade on any packages at that moment.

The full stop breakpoint occurs in the _reloader.py file on the sys.exit(3) line.

def trigger_reload(self, filename: str) -> None:
        self.log_reload(filename)
        sys.exit(3)

Here the traceback (it feel incomplete due to VS Code...)

Exception has occurred: SystemExit

Stupid me... It was my VS Code config, which I set to debug not just my code, due to a previous bug in another modules that I wanted to debug. I reverted to the default to debug just my code and now all is good. I'm closing it myself, but leaving for the posterity of that mistake.

This was the rubber duck debugging in action! :)

Regards!
