How do I return custom HTTP error codes?

[Swanand-Wagh]

I am using next safe action to call my server actions. The errors are being shown on screen properly but the network tab still shows 200 for a "USER ALREADY EXISTS" instead of 400 or 409. Even when I tried returning my custom error from the action, the network tab still shows 200. How do I handle this?

[viniciusvts]

maybe:

import { createSafeAction } from 'next-safe-action';

export const myAction = createSafeAction(async (input, context) => {
  // logic here
  if (userAlreadyExists) {
    context.res.status(409); // status code 409
    throw new Error('USER ALREADY EXISTS');
  }
  // other logic
});

this help you?

You can't return a different HTTP code. It's either 200 or 500 (when an error occurs). This limitation comes from React itself, so it's not related to this library.

So then why would anyone use server actions? Won't everyone prefer API routes? Because if for all errors, I'm receiving 200 in the network tab, won't it be a bad practice?
