Back End Development and APIs Projects - Replit

I’ve “skipped” the first test since the replit template provided didn’t work. I’ve made my code but I can’t test it and apparently that’s a problem with the whole “Back End Development Projects”

You can’t run it, or at least, I can’t. Even from fresh templates it doesn’t work, Tried several times, adding packages and whatnot but idk what’s wrong. I’m new with this technology and I have no idea how to fix it.

I’m using Opera GX. I don’t know if that’s relevant but after Replit cloned all the necessary data to the template, it’s unable to run in any way shape or form. That’s not the first time I had problems with Replit, in past challenges I had to make another post and the fix was nothing more than a simple update since the template provided was an older version for some reason

Hope someone that’s used to code with this kind of program can help me find a solution, thanks
