Hey, I’m trying to set up my django project following this tutorial (Getting Started · Fly Docs), and it works fine locally, but deploying it gives me the error that ‘ModuleNotFoundError: No module named ‘psycopg2’’ and it keeps looping until it crashes. It also tells me that it’s listening on the wrong port, even though I only tell it to listen on port 8000 in every doc. I’ll share my documents below, tell me if you need to see anything else.
