Hi,

I’ve opened an internal ticket to track this bug and the fix should go into our next release which is due in the next couple of weeks.

As a potential workaround, do you have any reflections on datasets that no longer exist? Dropping them should hopefully let you finish the upgrade. If you are fine with rebuilding all reflections, you could also drop them as that should also unblock you.

thanks,
Doron
