3780404 - Username update via OData user API fails for onboardees with error code 28 - onboarding

Username update via API is failing to update with the error message: "Failed to add/update user [the id]: General Error with error code - -28. with the index 0"

SAP SuccessFactors Onboarding

1. Hire the candidate from the Manage Pending Hires screen.
2. Attempt to update the username in the system for the not-yet-converted onboardee using the OData User entity.
3. Observe the error: "Failed to add/update user [the id]: General Error with error code - -28. with the index 0".

The OData User API was used for a user still in external/onboarding status (not yet converted and not present in the UDF file).

For users still in external/onboarding status, perform updates using the OData ExternalUser API instead of the User API.
