I have a Nextjs project that I am trying to deploy.
My build script is:
"scripts": {
"build": "next build",
"postbuild": "pnpm run build:post",
}
In the post build script I am trying to access index.html build output file at .next/server/app however the file is not accessible at the expected location.
In my local development environment the build output file is accessible from the post build script.
A static route at app/static.json/route.ts is trying to access the build file. So maybe the build file is unavailable when the static route is being built?
But I don't understand why it works locally, even after clearing .next folder
I have attached the build log below
