Prisma

I've just installed Prisma and am working with the basic TypeScript backend boilerplate. I'm getting this error when I run prisma deploy. It's stopping the prisma.ts file from being generated: ```Deploying service `backend` to stage `dev` on cluster `local` 38ms
Service is already up to date.

Hooks:
Checking, if schema file changed 72ms
Writing database schema to `src/generated/prisma.graphql`  1ms
Running $ graphql prepare...

 ▸

```

Not sure what's going wrong here in the prisma.graphql: ```type BatchPayload {
  """
  The number of nodes that have been affected by the Batch operation.
  """
  count: Long!
}```
