Heroku 产生错误 H10 并导致应用程序崩溃

Question

I'm using nodejs + reactjs + express + mongodb

Deployed my backend on another server and its works perfectly fine.

But when i accessing frontend it showing "H10" error and when i run this same project using heroku local its works perfectly fine.

My package.json

{
  "name": "ecommerce",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.5.0",
    "@testing-library/user-event": "^7.2.1",
    "braintree-web-drop-in-react": "^1.1.1",
    "concurrently": "^5.2.0",
    "react": "^16.13.1",
    "react-dom": "^16.13.1",
    "react-router-dom": "^5.1.2",
    "react-scripts": "3.4.1",
    "react-stripe-checkout": "^2.6.3"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject",
    "heroku-postbuild": "npm run build"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "engines": {
    "node": "10.x",
    "npm": "6.x"
  }
}

Logs that i get:

Also run heroku run node console

Output (incase it required):

internal/modules/cjs/loader.js:638
    throw err;
    ^

Already tried solution of First Heroku deploy failed `error code=H10` but it didn't work

Answer 1

Same problem for me, and after following the steps bellow it worked perfectly:

First try and install serve

npm install serve --s

then replace your scripts in the package.json by this:

"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"
}

after that add, commit and push to heroku
