Services published with a GUID key field that is not nullable fails to add related records in ArcGIS Pro.

解决办法

1. Add a new GUID field to the table, and set the Allow Null Values to Yes.
2. Calculate the old GUID values to the new GUID field.
3. Delete the relationship (Feature Class to Table).
4. Delete the old GUID field.
5. Create a new relationship class to replace the one deleted in step 3.
