REST API v1: "Invalid value for field 'item'" error when creating Assembly Build with lotnumberedass

in Ask A Guru 7 comments

Issue Summary

I'm encountering a persistent HTTP 400 error when attempting to create an Assembly Build via REST API v1 for a lotnumberedassemblyitem. The error message is:

"Invalid value for the resource or sub-resource field 'item'. Provide a valid value."

However, manual creation of the same Assembly Build through the NetSuite UI succeeds without any issues.

Environment

  • NetSuite Account: Sandbox (XXXXXX_SB1)
  • API: REST API v1
  • Authentication: OAuth 1.0 (HMAC-SHA256)
  • Item Type: lotnumberedassemblyitem
  • Item ID: 1234 (masked for security)
  • Component Item ID: 5678 (masked for security)

Request Details

Endpoint: POST /services/rest/record/v1/assemblybuild

Request Body (with all required fields based on documentation):
