Prisma

Hi all, with prisma client, how to return the entire SubscriptionPayload by example
```
type PostSubscriptionPayload {
  mutation: MutationType!
  node: Post
  updatedFields: [String!]
  previousValues: PostPreviousValues
}
```
from one subscription like
```
type Subscription {
  posts: PostSubscriptionPayload
}
```
?

I tried this:
```
  posts: {
    subscribe: async (parent, args, ctx) =&gt; {
      return ctx.prisma.$<http://subscribe.post|subscribe.post>()
    },
    resolve: payload =&gt; {
      console.log(payload)
      return payload
    }
  }
```
But in the resolve function I receive only the mutation Type, all others fields are null, whatever is the mutation type.

how does your subscription query look like?

```
subscription {
  posts {
    mutation
    node {
      title
    }
    updatedFields
    previousValues {
      title
    }
  }
}
```
