Prisma

I am running into the following error 
```
Hooks:
Checking, if schema file changed !
 ▸    Mutation fields must be an object with field names as keys or a function which returns such an object.

Get in touch if you need help: <https://www.graph.cool/forum>
To get more detailed output, run $ export DEBUG="*"
```

On `prisma deploy` after the line "Your GraphQL database endpoint is live"

And I think it is not getting deployed.

```
divyendusingh [prisma-backend]$ prisma --version
prisma/1.0.10 (darwin-x64) node-v9.4.0
```

#Help

UPDATE: This got resolved after I moved back to node 8.4.0
Will confirm if this is a bug and raise an issue :thumbsup:
