NetSuite Error Codes You Will Actually Meet

The error codes that come up most while developing on and integrating with NetSuite, what each one means, and where to look for the detail.

NetSuiteErrorsSuiteScriptDebuggingIntegration

NetSuite errors arrive as uppercase codes. They are consistent, so once you know a handful of the common ones your investigation time drops sharply — the code already tells you which layer the problem is in.

While writing scripts

CodeMeaningCheck
SSS_MISSING_REQD_ARGUMENTA required argument was not suppliedParameter names and spelling; fieldId typos are common
SSS_INVALID_API_USAGEThe API was called in a context that disallows itSome modules are not available in Client Scripts
SSS_USAGE_LIMIT_EXCEEDEDThe governance allowance ran outAPI calls inside a loop
SSS_TIME_LIMIT_EXCEEDEDExecution exceeded the time limitMove the work to Map/Reduce
SSS_INSTRUCTION_COUNT_EXCEEDEDToo many instructions executedA loop that never terminates
UNEXPECTED_ERRORAn internal failure with no clear categoryRead the detail in the Script Execution Log

While accessing data

CodeMeaningCheck
RCRD_DSNT_EXISTThe record was not foundWrong internal ID, or the record was deleted
INVALID_FLD_VALUEThe field value was rejectedData type, or a list value that does not exist
INSUFFICIENT_PERMISSIONThe role lacks permissionRole permissions, not the credentials
USER_ERRORA business validation refused itThrown by a script or workflow; read the message

While integrating from outside

CodeMeaningCheck
INVALID_LOGIN_ATTEMPTAuthentication was refusedRealm / account ID, especially the Sandbox suffix
INVALID_LOGIN_CREDENTIALSCredentials wrong or revokedThe token is still active and its role unchanged
NONEXISTENT_FIELDThe requested field does not existThe internal field name on the REST endpoint

Where to find the detail

  • Script Execution Log — for SuiteScript errors; filter by script and time of the incident.
  • System Notes on the record — to see who changed what, and when.
  • Workflow History — when it is a workflow refusing, not a script.
  • Login Audit Trail — for integration authentication failures.
