The migrtion works fine xcopy used =1 but the populator log reports this at the end:

1. On HPE 3par iscsi datastore a vm called mtv-test-rhel-8-10 was migrated to OCP 3par storage class via copyoffload.  
2.The migration completed, he VM is up on OCP side, xcopyused=1 so we know xcopy was used.
3. But the populator log shows an odd error, just wanted to mention it maybe work investigating or might be fluke (not sure) 

Migration passes fine, populator log reports the error mentioned on description. 

Understand why this error happens avoid it and have it vanish from the log.
