Stuck on the last stage of the GraphQL course

[bluabaleno]

Hey there, I'm not too familiar with JWT token and I can't seems to figure out how to create a new users with the admin token.

I thought you were suppose to modify the GraphQL schema to add

extend type Customer @auth(rules: [{operations: [CREATE, UPDATE, DELETE], roles: ["admin"]}])

But I can't seem to use mutation to create a new Customer still?

Any help?

Can you share the request header and the GraphQL mutation you're trying?

[bluabaleno]

Yep sure thing.

Http request header:

{
  "authorization" :"Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJCb2JMb2JsYXc3Njg3Iiwicm9sZXMiOlsiYWRtaW4iXSwiaWF0IjoxNTE2MjM5MDIyfQ.f2GKIu31gz39fMJwj5_byFCMDPDy3ncdWOIhhqcwBxk"
}

GraphQL mutation:

mutation {
  createCustomers(
    input: [
      {
        username: "BookWorm"
        reviews: {
          create: [
            {
              rating: 10
              text: "Why not"
              book: { connect: { where: { isbn: "190962151X" } } }
            }
          ]
        }
        orders: {
          create: {
            books: {
              connect: [
                { where: { title: "Ross Poldark" } }
                { where: { isbn: "1119387507" } }
                { where: { isbn: "1492047686" } }
              ]
            }
            shipTo: {
              create: {
                address: "Nowhere"
                location: { latitude: 55.6122270502, longitude: 12.99481772774 }
              }
            }
          }
        }
      }
    ]
  )
}

Here is my GraphQL Schema for good measures:

}

extend type Order {
  subTotal: Float @cypher(statement:"MATCH (this)-[:CONTAINS]->(b:Book) RETURN sum(b.price)")
  shippingCost: Float @cypher(statement:"MATCH (this)-[:SHIPS_TO]->(a:Address) RETURN round(0.01 * distance(a.location, Point({latitude: 40.7128, longitude: -74.0060})) / 1000, 2)")
  estimatedDelivery: DateTime @ignore
}

extend type Order @auth(rules: [{allow: {customer: {username: "$jwt.sub"}}}, {roles: ["admin"]}])

type Customer {
  username: String

}

"CreateCustomersMutationResponse!\" must have a selection of subfields. Did you mean \"createCustomers { ... }\"?"

Seems like you're having issues with the mutation itself and not JWT.

did you specify what data should be returned.. Looks like you need to add the fields that need to be returned by the mutation.

add what's inside the '{}' like this;

mutation{
Customer(
 // add you params here
){
  username
  orders{
   orderID
   placedAt
   shippingCont
   ...
   }
  reviews{
    rating 
    text
    createdAt
    ...
  }
 recommended {
   isbn
   title
   price
   ...
  }
}
}
