There was an error trying to run your application in FastBoot. (vanilla install)

The following error pops up on a fresh install of ember + fastboot. I assume things aren’t supposed to explode when doing simple text changes while fastboot is running.

There was an error trying to run your application in FastBoot.

This is usually caused by either your application code or an addon trying to access an API that isn't available in Node.js.
Based on the stack trace, it looks like the exception was generated in node_modules/ember-cli-fastboot/node_modules/fastboot-express-middleware/node_modules/fastboot/src/ember-app.js on line 245.
The exception is probably coming from your app. Look at this file and line number to determine what is triggering the exception.

The full stack trace is:

Couldn't find /Users/bsilva/ember/fastsample/dist/package.json. You may need to update your version of ember-cli-fastboot.

Dependencies

Reproduce

1. ember new [projectname]
2. ember install ember-cli-fastboot
3. ember generate route index
4. add a string above {{outlet}} in the generated index.hbs
5. ember fastboot --serve-assets
6. verify everything is work on localhost:3000. Should be good.
7. add another part to the string and hit save.
8. Explosions

Closing this. ember s should resolve the watch issue.
