Firestore create mutation gives me "is not a valid Document" error

[jonesnc]

Describe the bug
My GraphQL Schema looks like this with FirebaseDataSource set up.

type User @GQLifyModel(dataSource: "firestore", key: "users") {
  id: ID! @unique @autoGen # auto generate unique id
  username: String!
  email: String
}

Here's my index.js file:

const { Gqlify } = require('@gqlify/server');
const { ApolloServer } = require('apollo-server');
const { readFileSync } = require('fs');
const { FirestoreDataSource } = require('@gqlify/firestore');
const cert = require('./gqlify-firebase-adminsdk-a22pq-f37440b45b.json');
const databaseUrl = 'https://gqlify.firebaseio.com';

// Read datamodel
const sdl = readFileSync(__dirname + '/demo.graphql', { encoding: 'utf8' });

// construct gqlify
const gqlify = new Gqlify({
    sdl,

    dataSources: {
        firestore: args => new FirestoreDataSource(cert, databaseUrl, args.key)
    }
});

// GQLify will provide GraphQL apis & resolvers to apollo-server
const server = new ApolloServer(gqlify.createApolloConfig());

// start server
server.listen().then(({ url }) => {
    console.log(`🚀 Server ready at ${url}`);
});

When I try to run a createUser migration with:

mutation {
  createUser(
    data: {
      username: "newuser",
      email: "email@example.com"
    }) {
      id
    }
}

Gives me this error:

{
  "data": {
    "createUser": null
  },
  "errors": [
    {
      "message": "Argument \"data\" is not a valid Document. obj.hasOwnProperty is not a function",
      "locations": [

          "column": 3
        }
      ],
      "path": [
        "createUser"
      ],
      "extensions": {
        "code": "INTERNAL_SERVER_ERROR",
        "exception": {

            "    at Object.next (/sandbox/node_modules/@gqlify/firestore/lib/index.js:13:53)",
            "    at /sandbox/node_modules/@gqlify/firestore/lib/index.js:7:71",
            "    at new Promise (<anonymous>)",
            "    at __awaiter (/sandbox/node_modules/@gqlify/firestore/lib/index.js:3:12)",
            "    at FirestoreDataSource.create (/sandbox/node_modules/@gqlify/firestore/lib/index.js:125:16)",
            "    at CreatePlugin.<anonymous> (/sandbox/node_modules/@gqlify/server/lib/plugins/create.js:137:55)"
          ]
        }
      }
    }
  ]
}

The obj.hasOwnProperty is not a function error may be due to graphql's usage of Object.create(null) when constructing args. See: graphql/express-graphql#177 (comment)

hi @jonesnc should be fixed at version v1.0.11.

btw, you should move the firestore secret in your sandbox by using their secret key feature.
