Has anyone successfully deployed yet?

Hi,

I just start using the starter and it works great, awesome react starter. I've configured everything in firebase.google.com and .env files, following the readme and deployment guide here: https://github.com/kriasoft/react-firebase-starter/wiki/deployment.

But my problem is that when I want to build and deploy, no html files are produced, not even index.html. I've not modified anything except for .env file.

I've logged the details below, anonymizing them with < your site > and < your project > labels.
node: 10.16.0, npm: 6.9.0

The project was built assuming it is hosted at .
You can control this with the homepage field in your package.json.

The build/public folder is ready to be deployed.
You may serve it with a static server:

yarn global add serve
serve -s build/public
```

2) yarn deploy-prod
Comments: the app exists with firebase.google.com, not with cloud appengine though
```
yarn run v1.17.3
$ firebase --project= deploy && node ./scripts/post-deploy --env=prod

There was an issue deploying your functions. Verify that your project has a Google App Engine instance setup at https://console.cloud.google.com/appengine and try again. If this issue persists, please contact support.

4) firebase deploy --only hosting
comments: works fine, it registers and loads images and favicon.ico to the remote firebase server, but no html files are produced inside ./build/public
```

```
5) firebase serve --only hosting
This produces the same result as deploying to firebase servers,
```
i hosting: Serving hosting files from: public
✔ hosting: Local server: http://localhost:5000

```

- You may be able to run "npm run build" in your functions directory to resolve this.

```

Start by reproducing the reported `react-app build`, `yarn deploy-prod`, and Firebase deployment commands with the documented `.env` setup. Inspect the stack traces in `build/server.js` and the `scripts/post-deploy` entry point, then compare the deployment guide with the observed Firebase Hosting and Functions behavior. Done means the build produces the expected HTML and the documented deployment path completes successfully.
