Notice the top of the error: it says collecting brawlstats 2.2.2 even though you specified 2.3.0 in your requirements.txt, seems like something is wrong with heroku/your requirements.txt but I'm not sure

[thecaralice]

I updated it, changed requirements and tried one more time, but forgot to change error text

Lol it works now
