Vercel

Describe the Bug

When having a simple file system route like such

/pages

• /api
• /user
  • [id].ts
  • login.ts

I've noticed that when running the following configuration locally it works fine. and even when running yarn build && yarn start it still works fine. But when running on vercel. I always get the following error

You will see that the path is being matched to the [id] field and not the login field. But when run locally

which is extremely odd. A piece of useful information may be that [id].ts is an edge function while login.ts is a serverless function.

Expected Behavior

/api/user/login should match to login.ts and not [id].ts in vercel.

Link to reproduction

None

To Reproduce

npx create-next-app my-app

// /api/user/login.ts

export default async function handler(req, res) {

res.json({hello: 'world'});

}

// /api/user/[id].ts

export const config = {

runtime: 'experimental-edge',

};
export default async function handler(req) {

return new Response('Hello World');

}

npx vercel

The 500 error is from the code i have in the [id].ts not taking login as a valid id. in the replication example it will still return 200 but with 'hello world' as the response instead of

{ hello: 'world' }

Hi, I was seeing a similar issue #39266 which appears to be fixed in 12.2.5-canary.0, and you've said you're testing on 12.2.2. Does the issue still happen on the latest canary?

[Artrix9095]

I just tested 12.2.5-canary.0. Still no good

My main issue is why it this happening specifically on vercel but works fine locally

I could actually reproduce this locally, so investigating. 👍 Looks like the edge dynamic routes have a different priority than non-edge routes
