THe replit package includes it's own Flask fork. Instead of using from flask import Flask use from replit.web import App and use app = App(__name__) instead of app = Flask(__name__). This flask fork adds a few new features like login with replit for your site. See its docs here https://replit-py.readthedocs.io/en/latest/index.html

@xfinnbar File "/usr/lib/python3.8/signal.py", line 47, in signal
handler = _signal.signal(_enum_to_int(signalnum), _enum_to_int(handler)), this is the last file mentionned in the log before the error message

@romainkarpinski I forked the repl and fixed it, copy across my pyproject.toml file and keep_alive.py file. https://replit.com/@xfinnbar/BOT#keep_alive.py
