Why does PATCH on customer return X-NetSuite-PropertyValidation header?

edited Jun 2, 2025 2:35PM in Ask A Guru 3 comments

I am making a PATCH request to update a customer record. If my request payload includes (among other fields):

 "defaultShippingAddress": null

I get a 204 No Content (success) status as expected, but the response also includes the header:

X-NetSuite-PropertyValidation: Unknown field name defaultShippingAddress. The field does not exist on this record instance

I guess I need help interpreting this message. "Unknown field name" seems misleading to me, since the field *is defined* in the OA3 metadata for customer: https://system.netsuite.com/help/helpcenter/en_US/APIs/REST_API_Browser/record/v1/2023.1/index.html#/definitions/customer .

How should I interpret this message in the response header?
