Prisma

I don't know why, my schema seems to be fine at <https://github.com/jcortes/api-hotels/blob/master/types.graphql>

<https://github.com/jcortes/api-hotels/blob/master/types.graphql#L66>

needs to say
`subcategories: [Category!]! @relation(name: "CategorySubcategories")`

instead

also see <https://github.com/graphcool/graphcool/issues/778>

ok thanks I have changed that part in my code, but now I'm getting another error:
```
graphcool diff
Getting diff for cj8p0bbro002h01591gyfmesw with target default.... ✔
There are issues with the new project definition:

  Global
    ✖ Could not create serverless function for 'signup'. Ensure that the code is valid
```
Do you have any idea, what could be the problem?

Ok, I ran again ```graphcool diff``` and apparently it's working now
