Comment 1 RHV bug bot 2019-10-31 08:21:32 UTC

the same exception is thrown in another scenario while nothing updated in the Edit VM window , just open and close:

1. on cluster create Label1 - VM1, VM2 and Label2 with VM1, VM2, VM3.
2. Click on VM3 in Compute/VMs window, open Edit Virtual VM window/Affinity Labels. Change nothing and close.

Result: the exception is thrown.
