Describe the bug

File upload with yoga and nextjs works fine if its app router, but in pages legacy router it does not work as expected ... while using bodyParser: false it results with 500 error saying

TypeError: RequestInit: duplex option is required when sending a body.
    at new Request (node:internal/deps/undici/undici:7368:19)

and if I remove bodyParser:false I get a file response that is missing most of its built-in functions like stream and arrayBuffer

Hi @mstfash and thank you for the report

Sorry but I'm not adding a lot here but just labeling it according to our new Contribution Guide and issue flow.

It seems already got into stage 1 thanks to your reproduction! Thank you for that!

Now in order to advance to stage 2 we'll need a failing test, would be great if someone could help progress the issues through the stages.

Thank you and sorry that this comment is not a complete solution (yet).
