just curious, wouldnt it be possible to avoid creation of node instead of remove it ?

Node is created away ahead in the inclusion process. I am not sure if it is feasible to avoid creation.

The issue was more that the variable length bitmask was not processed correctly, and therefore the supported type was not populated correctly.
It was fixed in 1.5.0.
Note that this solution does not feel right, you are "removing the device functionality" by erasing the supported types... and there is still a risk that this SUPPORTED_NOTIFICATION_TYPES attribute get re-spawned at each system restart by zwave_command_class_notification_on_version_attribute_update()
I'd suggest to close this PR.

When the notification frame of the command class contains more than two bit masks, the SUPPORTED_NOTIFICATION_TYPES node stays undefined. Consequently, the ZPC (Z-Wave Protocol Controller) makes repeated attempts to retrieve the supported notification type from the device. This continuous loop causes the device to remain in an "Online interviewing" state for an extended period.
