Why did you get this error?
You attempted to push an incorrect value to a restricted picklist (for instance, you attempted to update a field with X linked to a picklist that only accepts A, B, or C).
How can you fix the error?
Option 1: Make sure your mapping does not allow incorrect or irrelevant values to a restricted picklist; for example, map only from a drop-down with dynamic values from the field.
Option 2: Change the picklist to be unrestricted in the Salesforce setup.
