Multipart upload fails with throttleit module export error

[Type-32]

Describe the bug
Multipart upload handling emits weird package related bug (on the frontend console, no errors on backend) when trying to upload the file:

XHRPOST
http://localhost:3000/api/upload/create/User Roles.pdf
[HTTP/1.1 400 Server Error 2048ms]

Uncaught (in promise) FetchError: [POST] "/api/upload/create/User Roles.pdf": 400 Server Error

env variables are there but just somehow can't get it to work.

Steps to reproduce
Steps to reproduce the behavior:

1. Go to https://github.com/Type-32/mpuupload-moduledefault-repo and clone the reproduction repo
2. Set your Vercel Blob read write token in .env
3. Use bun or pnpm to install and run the project
4. See error

Expected behavior
The file should've be uploaded to the blob storage; The test file I used to upload, "User Roles.pdf", is a standard pdf of 47KB in size.
