As it says it seems that index.js is missing but I surely have it in the repo that I pushed... I don't know what's going on.

Update: so I logged in to heroku bash and uses ls command. It seems index.js is present.

~ $ ls
LICENSE  README.md  index.js  node_modules  package-lock.json  package.json  test.js

still giving that error though.

CodePudding user response：

Your start script needs to include the full command to run, not just the name of your main file:

"scripts": {
  "start": "node index.js"
}
