Unexpected Error

UNEXPECTED_ERROR is a generic NetSuite error, so diagnosis depends on the API call, execution context, and input data at runtime. These are recurring causes we see in real support work.

Common SuiteScript Triggers

1. Loading a file with an invalid internal ID.
2. Using the N/email module when the author or recipient lacks an email address.
3. Merging email or PDF templates while passing a JavaScript string instead of a numeric template ID or RecordRef.

Quick Triage Approach

• Confirm record IDs and parameter types before API calls.
• Validate required fields and related records exist.
• Re-run with narrower scope (single record, smaller batch, or one parameter set) to isolate the failing input.
