Well, if I had to go from the error you get, https://err.sh/vercel/vercel/now-next-routes-manifest, it looks like your export app is having issues with:

• For next export users: do not override the "Output Directory", even if you customized the next export output directory. It will automatically detects the correct output.

or

• In rare scenarios, this error message can also be caused by a Next.js build failure (if your "Build Command" accidentally returns an exit code that is not 0). Double check for any error messages above the Routes Manifest error, which may provide additional details.

Have you got any special next.config.js? How does your package.json scripts look like?

It's finally working absolutely fine thank you @icyJoseph
