How to resolve "Response body object should not be disturbed or locked"?

Describe the bug

Started getting this error when trying to authenticate. I am unsure what's causing it.

Code around this is super basic and was working before:

export const action = async ({ request }: ActionFunctionArgs) => {
  const formData = await request.formData();

  const submission = parse(formData, {
    schema: FormDataZodSchema,
  });

  if (submission.value && submission.value.intent === 'sign-in') {
    try {
      return await authenticator.authenticate('user-pass', request, {
        context: {
          formData,
        },
        successRedirect: '/app',
        throwOnError: true,
      });

// ...

Seems like a bug in Remix https://github.com/remix-run/remix/discussions/8315

This is not a bug in Remix, you can only read the request body once, since you’re calling request.formData() and Remix Auth also do it it fails.

If you want to read the body before calling Remix Auth you need to first clone the request with request.clone().formData().

It was working just fine before migrating remix version:

-    "@remix-run/dev": "^2.3.1",
-    "@remix-run/node": "^2.3.1",
-    "@remix-run/react": "^2.3.1",
-    "@remix-run/serve": "^2.3.1",
+    "@remix-run/dev": "^2.4.0",
+    "@remix-run/node": "^2.4.0",
+    "@remix-run/react": "^2.4.0",
+    "@remix-run/serve": "^2.4.0",

But good to know. Thank you!
