can I write errors from the reduce stage into the summarize stage?

AI generated answer (using internal Slack threads):

Yes, you can write errors from the reduce stage into the summarize stage in Map/Reduce SuiteScript. When an error occurs in the reduce stage, you can throw a custom error and it will be captured in the summarize stage. The summarize stage has a native error iterator that will catch any error, whether it's thrown manually or occurs naturally. Here is a basic example of how you might structure your code to throw an error in the reduce stage:

javascript
if (!value) {
  throw error.create({
    name: 'MY_ERROR',
    message: 'My custom error message',
    notifyOff: false
  });
}

In the above code, if

value

is not truthy, a custom error is thrown. This error will then be caught by the error iterator in the summarize stage. However, please note that throwing an error in the reduce stage will also cause the error to appear as a system error in the Map/Reduce stage. If you want to stop the script from running further reduce stages for other keys when an error occurs, you can use the

exitOnError

option as mentioned in the NetSuite Help Center: exitOnError. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
