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

I face the same problem, it has worked for me.

add "serve" to application.

example: npm add serve or yarn add serve

after change scripts in package.json

"scripts": {
  "dev": "react-scripts start",
  "start": "serve -s build",
  "build": "react-scripts build",
  "heroku-postbuild": "npm run build"
}
