empty `apiGroup` in the VolumeReplication CR causes error

Do you mean the VolumeReplication CR? Also, can you paste in the command that showed you this log? I checked the operator pods and some other pods after setting apiGroup to "" but can't seem to find this error message, although I think it's worth mentioning that ever since I did that, the status is stuck at Replicating as you can see below.

Looks like this is not happening, @sp98 can you please verify it once?
