Hello, I can’t have the Backend working with this version ( neither the 21.6)
I have a nullPointerException at startup

Hi Siden,
Thanks for the info. I was not fully awaret that Config.getProperties() could be null. Can you check if the following pull-request fixes the problem for you?
Thanks
Stefan
thanks, I don’t have the nullPointerException anymore.
But my backend is blocked at this stage

Are you sure you have a valid configuration for OpenEMS Backend? It just seems like no Components are started.
The Backend works fine with this patch in the Gitpod environment based on Docker: Gitpod - Dashboard
Ok it was a wrong path for the felix dir.
