Does not work with angular-cli: content.charCodeAt is not a function

I generated a barebone app with angular-cli@1.0.0-beta.11-webpack and tried to deploy it with now:

```
ng new ng-sample
cd ng-sample
npm install --save angular-cli@1.0.0-beta.11-webpack
ng init
now
```

I get the error message: 

`content.charCodeAt is not a function`

Here is the link to the app: https://ng-sample-heemmtsdjo.now.sh/
