Locally, my Twitter bot runs fine but when I deploy it on Heroku it crashes with this error. Locally, everything is fine and when I run it, it tweets, likes and even retweets but on heroku it says it has crashed.

What can I do to correct this error and make the app run on Heroku? What could be causing this error?

  • Bots are malicious! what kind of bot is this? I'm joking, I had this same problem..but my case was different. This is pointing at a character encoding problem. https://stackoverflow.com/questions/21129020/how-to-fix-unicodedecodeerror-ascii-codec-cant-decode-byte – Conor Aug 23 '22 at 10:45
  • The beginning statement had me freaking out. It's just a Twitter bot. – kana natasha Aug 23 '22 at 11:26
  • I find it weird that it runs fine locally and even tweets but on Heroku it doesn't. I've tried adding encoding="utf-8" but the error still persits – kana natasha Aug 23 '22 at 11:39
  • are you using a runtime.txt file in your project directory? if not, make "runtime.txt" put it in your project directory and paste "python-3.9.13" in it. this will force Heroku to deploy with this version, it might fix the problem. – Conor Aug 23 '22 at 12:15
  • try with these other runtime versions if that one still kicks off the same problem: https://devcenter.heroku.com/articles/python-support#supported-runtimes – Conor Aug 23 '22 at 12:16
