PieFed script generating weird system e-mails?

I've successfully gotten PieFed up and running in its docker iteration and with help from folks here, I'm now backing things up as they should be! I noticed that cron is reporting an error in one of the scripts that is being called though, here is an example of the e-mail that I am receiving:

Subject: Cron <phoenix@phoenix> docker exec piefed_app1 bash -c "cd /app && ./send_queue.sh"

./send_queue.sh: line 3: venv/bin/activate: No such file or directory[2026-01-26 03:25:03,595] INFO in init: Started!

I've checked the contents of the script and the line in question appears to be trying to activate a Python virtual environment inside the /app directory, but it appears that this is failing? I'm not sure if that means the entire script is failing as well, but it's certainly generating a lot of e-mails! Unfortunately the Docker image doesn't include an editor of any kind, so I was unable to change the contents of the script, or to install an editor or virtualenv. I'm not sure how to proceed!
