How to Control HTTP Status Codes in NetSuite Suitelets?

NetSuite Suitelets do not offer direct functionality to explicitly set custom HTTP status codes within the http.ServerResponse object. For instance, attempting to return a 403 Unauthorized status code for authentication requirements is not directly achievable through standard Suitelet methods. The system typically returns a 200 OK status for successful executions. In cases of unhandled errors, the Suitelet may return status codes such as 400 Bad Request or 500 Internal Server Error, rather than a 206 Partial Content for general errors. The only viable workaround is to implement custom error management within the Suitelet's response body. This involves structuring the response payload (e.g., JSON or XML) to include custom error codes, messages, and other relevant details that can be parsed and interpreted by the client application. This approach allows developers to communicate specific error conditions and their nature effectively, even without direct control over the HTTP status line.
