Hello Netlify Community and Support,
I am deploying a Next.js application which is part of a Yarn monorepo to Netlify. The build and deploy steps are reported as successful in the Netlify dashboard, but when I try to open the deployed site URL, I receive an error.
Upon checking the function logs, I see the following error repeatedly:
May 5, 07:54:21 PM: ERROR Unhandled Promise Rejection {"errorType":"Runtime.UnhandledPromiseRejection","errorMessage":"Error: Cannot find module 'next/dist/server/lib/start-server.js'\nRequire stack:\n- /var/task/.netlify/dist/run/next.cjs", ...}
(This is the exact error message from my logs, timestamps may vary).
This indicates that a required Next.js server module is not being found when the serverless function is invoked at runtime.
My site URL: https://vedvaani.netlify.app/
Next.js project all deploy steps success, but when open preview site, it gives error.
Function log has error:
