#503

[lucvin]

Hi, i've fixed the extension error and now i have this error on the git ci and cannot commit

newdle/core/app.py:81:9: LOG004 .exception() call outside exception handlers | 79 | # message or the debugger while in development mode. 80 | raise # noqa: PLE0704 81 | app.logger.exception('Request failed') | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ LOG004 82 | return jsonify(error='internal_error'), 500 | = help: Replace with .error()

this has always been there and i don't know why it's bothering him now but it might need to be changed https://docs.astral.sh/ruff/rules/log-exception-outside-except-handler/

Maybe just add a noqa for now?
