scripts/run: line 180: [: -eq: unary operator expected

Not sure what this means, but I cannot access qbittorrent. I have it running with similar compose on a different system. But for some reason, with the same compose, I keep getting this issue:

I imagine you'd get that error if PORT_PERSIST is set to something unexpected. The Dockerfile sets it to 0 by default, and the script expects it to be either 0 or 1. I don't suppose you have it set to something non-numeric, or maybe an empty environment var? That could explain the error msg.

Strange, this is my compose, the only env vars are the PIA username and password:

That compose file will be setting PORT_PERSIST to an empty value. The script expects it to be a number, so is throwing an error when it encounters it. I haven't added anything to catch stuff like that, though it might be worthwhile doing so to stop it from potentially misbehaving.
