N/error Module in NetSuite: Custom Error Handling Guide

The N/error module lets you create and throw custom, descriptive errors in SuiteScript. Instead of generic JavaScript errors, you can create errors with meaningful names, messages, and user-facing messages.

Creating and Throwing a Custom Error

define(["N/error", "N/log"], (error, log) => {
  function validateOrder(amount) {
    if (amount <= 0) {
      throw error.create({
        name: "INVALID_AMOUNT",
        message: "Order amount must be greater than zero. Received: " + amount,
        notifyOff: false
      });
    }
  }

  try {
    validateOrder(-100);
  } catch (e) {
    log.error({ title: e.name, details: e.message });
  }
  return {};
});
