next-node webhook example fails in Vercel production environment

[KhudaDad414]

Description:

The webhook example provided at https://github.com/grammyjs/examples/tree/main/setups/next-node does not work correctly when deployed to Vercel. The following behaviour occurs:

• Production Timeout: The webhook callback function appears to run indefinitely, eventually causing a timeout on Vercel's serverless functions.

The example functions as expected in a local development environment.

Solution:

The issue was resolved by:

1. Moving the webhook route definition into the pages directory (to create an API route within Next.js).
2. using the next-js adapter for webhookCallback.

Possible Cause: The original setup might not be compatible with Vercel's serverless function execution model. or Next.js app directory API routes and the std/http adapter probably are not compatible.

Are you able to fix the example so that others can benefit?
