I´ve been building a bot and it works exactly as intended, but only for one Tweet. Then, it waits 60 seconds, and, if it doesn´t find a new Tweet to reply to (since it´s configured to reply to the most recent Tweet), it throws an error (it´s 400 as in “400: Bad Authentication Data”, but I think the issue is not that, since the bot posts on Twitter once without any issues. However, I do think it´s possibly some kind of Bad Request error). Whenever it crashes, I can just run in my command “python (botname).py” and it works once if there is now a new Tweet, but then, it crashes again. I want the bot to run properly by itself, so I would really appreciate some help! This is the code in my file:

Thank you really much!

Answer
A 400 HTTP error status code usually means Bad Request, which is likely the case here. When there’s not a new Tweet to reply to, the for loop isn’t entered, and check_mentions, the function itself, is returned. You then set it as since_id when its returned and use it as an ID the next time check_mentions is called. This probably ends up passing something like "<function check_mentions at 0x0000028E6C729040>" to the API as since_id.
