Panorama SDWAN issue during commit with errror message "failed to create sdwan cluster meta file: 'NoneType' object has no attribute 'node'"

Cause -->  This issue is directly related to high-availability configuration in SDWAN device in local device. If you are adding an standalone firewall as SDWAN device in Panorama with locally enabled HA configuration it will cause this problem.

Solution -> You can either remove local HA configuration in the firewall or tou can implement HA with 2 member and then you can setup SDWAN in both devices as an HA group in Panorama SDWAN settings.
