When trying to create a new record within conveyor, if selecting a related record through the built-in dropdown feature, a 400 error occurs if the name of the field doesn't exactly correspond to the list that needs to be queried.
For example, if there's a relation between a record "example" and "platform_area_type," but the field is named "area_type" in "example," (the model works fine with this implementation) the dropdown will parse the list of "area_type" as "area_type_list" rather than "platform_area_type_list," the actual list that needs to be queried.
The query works as expected in GraphiQL once "area_type" is changed to "platform_area_type."
