I got this error during deployment:
An unexpected error happened when running this build. We have been notified of the problem.

I've deployed 5 times but the error persisted.

The project is in Next.js 14.2.14, and it's able to build on local machine.
The only change to the codebase was to add a new redirect rule. But the build still failed after I commented out the code.

Is there something wrong with the deployment currently? Or how should I debug this? Any thought is appreciated!
