  madscientist5500 yes, my issue was due to mismatched Admin consent.. meaning I used the incorrect tenant domain in the consent URL. I also had an issue during one of my tests due to OAuth Application ID not being associated to the Migration Endpoint.
  
  All of my help came from emailing mailto:Email address removed. They were extremely helpful in determining the exact issue.
