onError: For 'VALIDATION' type errors, status code change does not work (200 is always returned)

[nadeemramsing]

What version of Elysia.JS is running?

"version": "1.0.17"

What platform is your computer?

Linux 5.15.0-88-generic x86_64 x86_64

What steps can reproduce the bug?

• Create a route /files POST
• Use type: {body: t.Object({file: t.File()})}
• In onError function, when code === 'Validation', set status to 400.
• Run app
• From Postman, do a request on the route with a form-data body without "file"

What is the expected behavior?

Return error and 400 status code.

What do you see instead?

Error is returned but status code remains 200.

Additional information

In fact, logger (HoltLogger) says "unknown status":

In my case, setting status code and even return a value (e.g. "TEST") does not work; 200 and Validation Error by type lib is returned. Execution gets there (console.log inserted and called just before the setting of status and return).

You can overrite error.status or return a raw Response object as a workaround:

.onError(({ code, error }) => {
  if (code === "VALIDATION") {
    // @ts-ignore
    // error.status = 400;
    return new Response(error.message, {
      status: 400,
      headers: { "Content-Type": "application/json" },
    });
  }
})

Thank you; I'll try that.

Working perfectly; thank you.

Please leave the issue open as it's a bug and needs to be fixed somehow.

set.status = 400 must either work or not be made accessible.

I gave you a workaround to make it work for you right away.
