Comment 3 Gregg Tanzillo 2018-05-08 13:12:59 UTC

I looked at the appliance with the customers Db and found an an orphaned instance in the relationships table. I deleted the bad instance and that resolved the error. 

You can have the customer do the same. Here are the steps -

On an appliance in the global region open a rails console and type in this command -

Relationship.find(3000000160358).destroy

That should fix it.
