I got error:

Not sure why need log_channel, but I open a new channel and use https://t.me/username_to_id_bot to find out the ID.
So I changed that line into:
LOG_CHANNEL = int(-1001478052015)

You put wrong code!
That will be LOG_CHANNEL = -1001478052015 !

I think you are deploying on your private server.

Even in that way it's not working
