When the Object 'Name' field has a Default Value set or is using auto-numbering, the 'Copy' action fails with an API error.
Steps to Reproduce:
Expected Results: When the user invoked the 'Copy' action from the UX, it should be successful.
Actual Results: An API-1039 Invalid Request URL Toast Message appears and the 'Copy' action fails. There is no additional information in the app log. The problem is that no payload is sent so the JSONParser returns null which leads to the resources getting set to null and the InvalidUrl message is sent. When only the ID field is auto-numbered, that works as expected.
Workaround: Do not set a Default Value or use auto-numbering on a Custom Object for the Name field if the 'Copy' action is going to be used.
Targeted Fix in Release 16.1.2
The API Toast error message will no longer appear.
The modal will be blank because the required Name & ID fields have existing values that will be copied over.
