Description

Pathname '/https,http://localhost:63450/api/chat' should have matched '/api/chat'

error when sending requests to the chat route with Next.js 14.0.2. This can be avoided by downgrading to Next.js 14.0.1.

Steps to reproduce -

1. Clone the Vercel AI SDK, Next.js, and OpenAI Chat Example
2. Configure the environment variable, install packages and run with vercel deploy, then submit a prompt - the app will work as expected
3. Update to latest stable release of Next.js with npm i next@latest
4. Run with vercel deploy - an error will be logged

⨯ node_modules/next/dist/esm/server/web/edge-route-module-wrapper.js (58:18) @ EdgeRouteModuleWrapper.handler ⨯ Invariant: no match found for request. Pathname '/https,http://localhost:63450/api/chat' should have matched '/api/chat'

@AlexIsMaking Are you using the useChat hook?

[AlexIsMaking]

@tgonzales yes I am, I haven't changed anything from the example project.

@AlexIsMaking I believe it is related to this issue https://github.com/vercel/next.js/issues/48295 Awaiting

@tgonzales ah, thanks for the heads up. I'll share some info on that issue too.

There are some differences though - I'm not using middleware and Next.js 14.0.1 is working for me, whereas that issue was opened for ~13.3.
