Hello!

There is a way to check if my deployed flow has an unknown/missing node?

Situation:  
I have a nodered application running in a docker container and sometimes the kubernetes deploy a new pod missing some node\_modules(dont know why...).  
We have a health check routine and I would like to know if any module is missing.
