Error: ENOENT: no such file or directory in Heroku

I had this issue when deploying a custom node cli app to heroku. Does anyone know why dist/index.html cannot be opened?

I finally found the solution. need to update production index path in web/index.js
const PROD_INDEX_PATH = `${process.cwd()}/frontend/dist/` to
const PROD_INDEX_PATH = `${process.cwd()}/web/frontend/dist/`
