I think there could be a small improvement in the JSON that comes back when trying to add an illegal collaborator (for example: someone has not yet accepted an invitation to a base).
This is the response I’m seeing:
{"error":{"type":"INVALID_VALUE_FOR_COLUMN","message":"Cannot parse value \\"\object Object]\\" for field Rep"}}
I suspect the ‘object’ part should be something else. :winking_face:
