The fetch works normally when I try in node

do u mean it works in Vercel Node.js runtime, but it fails Vercel Edge runtime?

No, when I try the same exact fetch request it works in NodeJS but when its runned in a api route it errors out

nextjs has a request and response body limit, (they are configurable)

for large files they are typically served from a presigned url

also if you deploy to a serverless provider like vercel, fetching and sending a 200mb file may take longer than 60s (which is the max time a function can run)

Where can I configure it?

Next config

In your root

Google for the terms I mentioned

And you’ll find examples
