steps to reproduce:
1 create a synched table, say Users and create one user
2 in another db add the synched User table
3 create a table, say Exam, that has a field that links to the user
4 verify that you can, from the Exam table, link a user from the synched table
5 from the API call the create method on the Exam table with the field user : [ user-rec-id ]
6 notice you receive an error 422 ‘Record ID user-rec-id does not exist’
expected result:
You should be able to create an Exam record from the API with a user linked to the synched User table
