[Bug]: Undefined in Middleware

[oga-sven]

What happened?

When trying to upload an image, i get an error that an imported util is not defined. I tried other solutions and imports but they get the same error. none of the imported functions work

What did you expect to happen?

I expected my utils to be defined

Version

"uploadthing": "^5.2.1"

Reproduction Steps

Below i have pasted my middleware. Without the auth stuff it works perfectly fine, I am using pnpm. Im not completely sure what to provide more than the middleware as its not something very specific. No matter what i import, be it a custom function from a different file or something from a library, i always get undefined.
This is only the case for imports, as same file functions work. more in the code below

Reproduction Repository

import { createUploadthing, type FileRouter } from 'uploadthing/next-legacy';
import permissionCheck from '../utils/nextAuth/permissionCheck';
import getAuthToken from '../utils/nextAuth/getAuthToken';
// import { getSession } from 'next-auth/react'; // Commented here. But this also returned undefined

const f = createUploadthing();

const sameFileTest = (testLog) => {
  console.log(testLog);
};

export const ourFileRouter = {
  imageUploader: f({ image: { maxFileSize: '4MB' } })
    .middleware(async ({ req, res }) => {
      sameFileTest('testing') //This works without a problem
      const token = await getAuthToken(req); // Its saying that this is undefined. 

      if (!token) throw new Error('Not authenticated');

      const response = await permissionCheck(token as string, 500);
      if (!response) throw new Error('Unauthorized');

      return { userId: 'userid' };
    })
    .onUploadComplete(async ({ metadata, file }) => {
      // This code RUNS ON YOUR SERVER after upload
      // console.log('Upload complete for userId:', metadata.userId);
      // console.log('file url', file.url);
    }),
} satisfies FileRouter;

export type OurFileRouter = typeof ourFileRouter;

Fyi i did now fix it by splitting the auth into a local function and letting that do the logic like the docs. But it seems weird to me that this is the intended way
