It sounds strange because node-red is in a container, rebuild does not help and it’s minor update back and forth with will cause the container log the error. I’m not aware any 3rd party modules installed inside node-red and my config is simple. But I will keep looking, need to disable auto update for now.

Thank you for you help.

That startup is fine.

Error: Cannot find module ‘nopt’

Is not part of this add-on, so I’m not able to tell you how it got into your system. I don’t manage that system.
