Link to the code that reproduces this issue

https://github.com/Ammar52501/test-rewrite

To Reproduce

  1. Clone the following repository: https://github.com/Ammar52501/test-rewrite

  2. Install dependencies and run the project locally:

    • bun install
    • bun run dev or bun run build && bun run start

  3. Verify that basePath and rewrites work correctly in local environment

  4. Deploy the same repository to Vercel

  5. Access the deployed app and observe that the rewrite no longer works

Current vs. Expected behavior

  • The deployed app on Vercel should behave the same as local development
  • basePath and rewrites() should work consistently in all environments

TL;DR

  • The issue with basePath and rewrites not working on Vercel deployment can likely be resolved by configuring Vercel to handle rewrites correctly.

Guidance

  • Review Vercel configuration to ensure it supports Next.js rewrites and basePath settings.
  • Check the vercel.json file for any missing or incorrect settings related to rewrites.
  • Verify that the next.config.js file is correctly configured for Vercel deployment, including any necessary settings for basePath and rewrites.
  • Test the deployment with a minimal vercel.json configuration to isolate the issue.

Example

No code snippet is provided as the issue lacks specific details about the configuration files.

Notes

The solution may depend on the specific versions of Next.js and Vercel being used, as well as the exact configuration of the next.config.js and vercel.json files.

Recommendation

  • Apply workaround: Configure Vercel to handle Next.js rewrites and basePath settings correctly, as the issue seems to be related to the deployment configuration rather than the code itself.
