I am creating Customer record in Zoho books, through Workflow\Custom Functions in Zoho book.  The input values are picked from custom module "cm_student_id" during edit and save events.

The Customer record is getting successfully created, however only the record is taking the "contact_name" data.  The Rest of the fields like first_name, last_name, etc.. are not getting populated.  But the missed values are available(log).

Attached the custom function and log for reference.  Please verify and advise.
