gunicorn not found in $PATH when deploying Docker

When I try to deploy Patrowl with pre-configured engines I get an error deploying:

pieter@supersecretstation:~/PatrowlManager$ docker-compose -f docker-compose.with-engines.yml up
patrowl-nmap is up-to-date
Starting patrowl-owl_dns ...

ERROR: Encountered errors while bringing up the project.

Any ideas on how to fix this?

I got it running by building engine-owl_dns container locally.

Clone https://github.com/Patrowl/PatrowlEngines
Use Dockerfile under engines/owl_dns
