Budget App's Unit Test Error

I have been working on this for a few hours assuming that I was missing something, but now I believe the testing may be to blame. I cannot figure out how to fix this.

Could someone explain it to me like I’m 5? Thanks! :slight_smile:


In the .replit file (it’s hidden, to see hidden files on replit click the three dots at the right of files tab, and then select Show hidden files) change the nix channel to stable-21_11

Thanks, friend! Can I ask why that solves the issue for future reference?

I’m afraid I don’t have explanation why 22_05 channel is causing troubles. Error from the screenshot suggests some kind of issue with the environment in which python runs when 22_05 channel is used. All I know for sure is that with 21_11 channel everything works fine.
