I'm attempted to insert a new record into a "grandchild table" via URL. I pass in the GUID into the foreign key field that links up with the Parent globalID. Upon submitting the survey, I receive the following error:
Failed to submit. Hide details
Everything works fine if I delete the parent-to-grandchild geodatabase relationship. If I have relationships between parent and child and then child and grandchild everything is good. But as soon as I try to have a relationship between parent-child and parent-grandchild, I get the error above.
Stranglely, I can add records to the grandchild directly from the parent just fine in Field Maps, so this seems to be unique to Survey123.
One option is just to adapt a workflow without these multiple relationships, but I'd prefer to keep them if possible.
