Based on our internal testing, this error will only be encountered when a Constituent record already has Constituent Appeals at the time of import. Constituents where the import does not error will have the Appeal and the Package imported properly.
If you encounter the above error and have recently changed your User Options, please restart RE7 and attempt your import again. If you continue to encounter errors after restarting RE7, please contact Support for assistance.

THANK YOU. You're a life saver. We were implementing the Omatic Luminate Connector the pas couple of weeks and our implementation specialist had me switch to appeal description during training as the person who will be processing these imports has her settings set to that. When I tried a monthly import I already had set up prior and got the error for the missing appeal description I put 2 and 2 together and switched my settings back to ID. But when I then started getting the "package must be valid" error over and over, I was at a complete loss. Your solution totally did the trick!
