Bug from #6018:
Creating a Collection Object (CO) through a Collection Object Group (COG), filling out its Paleo Context field, then saving causes an error.

2. Add a child CO
3. Expand new child CO and fill out the Paleo Context field - either through the search or query builder
4. Save COG and see error

Expected behavior
Should save input.
