Foreign Multivalued Group Transformation reports "Value cannot be null" for multivalued attribute with no members
Please see attached Broker configuration. The "MIM LMS Group Users" connector generates records for groups, with a multivalued field "PersonNumbers" that is then used by the "MIM LMS Person" adapter in a Foreign Multivalued Group Transformation to generate the DNs of the groups each user is a member of. When a group has no members, running an Import All on the connector causes a "Value cannot be null" error to be logged. If I change the source data to not include any groups with no PersonNumbers data then the error does not occur
As a workaround, I've inserted a dummy value into blank PersonNumbers field values as shown here:
I tried to replicate this issue in a simpler Broker instance, but I could not sorry.
