Hello, I'm a new beginner of Otree. I created my first app named "myapp" and when I used "otree zipserver" and went to the localhost website, it turned out "Application error (500) KeyError: 'myapp'". I had updated my otree to version 5 and also had run the code "otree remove_self""otree upcase_constants". What in "myapp" was just a simple survey for participants'gender.
Also, there was what said in cmd:
Exception in ASGI application

I don't know how to fix it. Thank you very much!
