"message": "Cannot read property 'xxx' of undefined"

Hi,
I followed your tutorial, and I get this issue: "message": "Cannot read property 'chat' of undefined" after creating an element (Chat).

here you have my code:

Subscription resolver

const Subscription = {
  chat: {
    subscribe: async (parent, args, ctx, info) =>
      ctx.db.subscription.chat({}, info)
  }
}

module.exports = {
  Subscription
}

mutation Create Chat

async function createChat (parent, args, ctx, info) {
  const userId = getUserId(ctx)
  args.data.author = {
    connect: {
      id: userId
    }
  }
  return forwardTo('db')(parent, args, ctx, info)
}

Datamodel

type Chat {
  id: ID! @unique
  createdAt: DateTime!
  updatedAt: DateTime!
  message: String!
  author: User
}

schema.graphql

type Subscription {
  chat(where: ChatSubscriptionWhereInput): ChatSubscriptionPayload
}

Any ideas where this issue might come from?
Thanks!
