Graphql Nested object: “must be Input Type but got”

I am trying to do a mutation on Graphql. I want to add another object in my query and mutation. My root query works fine but I had trouble with mutation. I am getting an error. This is the error: “The type of Mutation.addRestaurant(location:) must be Input Type but got: LocationType.”

This is my restaurant query

const restaurantname = new GraphQLObjectType({
  name: "RestaurantType",
  description: "This is Helsinki's Restuarent",
  fields: () => ({
    name: { type: GraphQLString },
    image: { type: GraphQLString },
    address: { type: GraphQLString },
    info_url: { type: GraphQLString },
    location: { // This is locationtype
      type: location,
      resolve(parents, args) {
        return parents;
      }
    }
  })
});

This is my locationtype object, where I added in restaurant type.

const location = new GraphQLObjectType({
  name: "LocationType",
  description: "Helsinki's locations with lat and long",
  fields: () => ({
    lat: { type: GraphQLFloat },
    long: { type: GraphQLFloat }
  })
});

This is my root query and it works fine:

const query = new GraphQLObjectType({
  name: "Rootquery",
  description: "This is Rootquery",
  fields: () => {
    return {
      restaurant: {
        type: restaurantname,
        args: {
          name: { type: GraphQLString }
        },
        resolve(parents, args) {
          //return restaurant.models.restaurant.find({ where: args });
          return parents;
        }
      }
    };
  }
});

This is the mutation which I don’t know how to add locationtype object:

const mutation = new GraphQLObjectType({
  name: "Mutation",
  fields: () => {
    return {
      addRestaurant: {
        type: restaurantname,
        args: {
          name: { type: new GraphQLNonNull(GraphQLString) },
          image: { type: new GraphQLNonNull(GraphQLString) },
          address: { type: new GraphQLNonNull(GraphQLString) },
          info_url: { type: new GraphQLNonNull(GraphQLString) },
          location: { type: new GraphQLNonNull(location) } //
        },
        resolve(parents, args) {
          let restaurantData = new restaurant({
            name: args.name,
            image: args.image,
            address: args.address,
            info_url: args.info_url,
            location: args.location
          });
          restaurantData.save();
        }
      }
    };
  }
});

This is second time Github issue. So, It looks mess. I am sorry for that.

@alakdam07 Check your types const restaurant = require(“./models/restaurant”);

addRestaurant: { type: new GraphQLList(**restaurantname**), args: { name: { type: new GraphQLNonNull(GraphQLString) }, image: { type: new GraphQLNonNull(GraphQLString) }, address: { type: new GraphQLNonNull(GraphQLString) }, info_url: { type: new GraphQLNonNull(GraphQLString) }, location: { type: new GraphQLList(locationInput) } }, I think restaurantname is not the type you are importing. Let me know if it helped!

Cheers

Had the same problem. The problem is that in the mutation you define address as type, on this line: address: { type: new GraphQLNonNull(GraphQLString) }, It should be defined as input instead, making it: address: { input: new GraphQLNonNull(GraphQLString) },
