Dynamic catch-all route also catches API routes

[ragnorc]

What is the problem?

I have a catch-all route in the pages folder: pages/[...params].tsx. Now, when I have an anchor tag pointing to my api routes (e.g. api/auth/google) or if I do Router.replace(/api/auth/google) the catch-all route pages/[...params].tsx is triggered where params=['api','auth','google']. Manually entering api/auth/google in the browser however correctly triggers the API route. Additionally, this issue seems to happen only in production (Vercel deployment).

What are detailed steps to reproduce this?

1. Create pages/[...params].tsx
2. Create API route.
3. Deploy to production (Vercel).
4. Redirect to API routes using anchor tag or Router.

@ragnorc sorry for the delay here. If it's only on Vercel, then I'm thinking it's a vercel bug because they handle routing in their platform.

Can you test with nextjs and see if it has the same issue?
