ZWave Handler for ManufacturerProprietary Command Class

Tried this with no luck. I know that the command should be "9100 (Manufactured Proprietary CC 91, command 00) but still getting an “event with a handler unnamed”.

I tried to add the error field in the driver template spec but this didn’t work as most probably I didn’t enter the field in the right place.

Any help would be appreciated.
