I was trying to run the backend server with the OpenDevin installation, however, every time I tried to use uvicorn opendevin.server.listen:app --port 3000 it said uvicorn is not recognized as an internal or external command, operable program or batch file.Then when I used python -m uvicorn opendevin.server.listen:app --port 3000it showed TypeError: unsupported operand type(s) for |: 'type' and 'NoneType'. How do I start up the port on the backend?
I tried to use 'python -m uvicorn opendevin.server.listen:app --port 3000' to start the port through OpenDevin, but it didn't work.
Check if you are running the first command in the python environment you created during the set up.
