Hi, I'm getting a 502 error in a very specific situation--when I try to append an object to a list, pythonanywhere hangs. There is only one object, and the list is empty, so it shouldn't be an issue of taking up too much resources. Anything from typing list += object, or list.append(object) causes it to load for a very long time and then respond with an error message. Any idea how to fix this?
