Adding a new spool to the AMS that is unknown to bambuddy results in the new spool not being added to the filament inventory.
the logs show this error repeatedly:

It works now with the new 0.2.2b2 image. I did not build from source, so I guess the published 0.2.2b1 image was not up-to-date. you can close the issue
