'Deployed project successfully, Heroku 503 error when trying to open in web

Was able to push my stack app to Heroku and have it deploy successfully with no error, but when opening the link it gives me a 503 error. I am curious to if I'm missing something in my package.json or my server is setup incorrectly. "heroku logs --tail" was able to show me the error, and the error below says im missing script start. I've checked my script in package.json but I am not missing the start script in my package.json and added the build script in my server package.json to build my React app. My full project is available here:

Your package.json file is missing the node js version declaration. Heroku would require it when building to target that specific version.

"engines": {
    "node": "14.x"
  },

See this link for more info. https://devcenter.heroku.com/articles/deploying-nodejs#specify-the-version-of-node
