Not Able to Update Manager - HRManagerEmailAddress via API after 24D Update?

Not Able to Update Manager in Resource Attribute HRManagerEmailAddress via REST API(crmRestApi) after Oracle Update 24D?

before we can update the said Attribute:
/crmRestApi/resources/latest/resourceUsers/{ResourcePartyNumber}/HRManagerEmailAddress

Body: { "HRManagerEmailAddress": "email@cx.com"}

but after the update, the result gives the request - Response: 400:
JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=JBO-29000: Unexpected exception caught: java.lang.NullPointerException, msg=null

Are there additional security roles/privileges required to perform this task?
