React app runs locally, crashes when on Heroku error code=H10

Question

The app runs fine after an \'npm start\' in windows, but when I pull from github into Heroku I just get an error.

package.json:

{
  \"name\": \"tic         


        

Answer 1

1.) npm install serve --save or yarn install serve --save in your terminal

"scripts": {
"dev": "react-scripts start",
"start": "serve -s build",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject",
"heroku-postbuild": "npm run build"
}

2.) copied the above code in place of previous code "scripts" in my package.json file

3.) git commit -am "new update"

4.) git push heroku master

• Note: the common problem is missing the first step.
