Why does this code not updating the Contract (Recordname) Field

Summary:
I am trying to update a field called Conract (RecordName) via the onFieldValueChangeCallbackChain. The RecordName sets a new value as per console logs but it is not updating the actual field in UI. Is there something wrong with my code?
