Parse Server 📡 GraphQL API
#1

Hi,

I am trying to solve this bug, GraphQL error when retur.

We are in the process to migrate to gql but we still use a lot of cloud function and want to make the transition as simple as possible but this issue give us headache… I have seen that we use SchemaDirectiveVisitor to find the @resolve but it looks like we don’t use parseGraphQLSchema.addGraphQLQuery for when we add the queries, could that be the problem?

#2

It looks that the array are being properly converted for the default queries but not when resolving results from cloud code functions.

#3

I found that the result of the resolvers returns the same format ( standard query result). But I can’t find where the query result is actually parsed and transformed to a gql result. For the default query. I think defaultGraphQLTypes.loadArrayResult(this, parseClasses); has something to do with…

I have a test written for problem,

`it(‘can resolve a custom query, that returns an array’, async () => {
const schemaController = await parseServer.config.databaseController.loadSchema();

    await schemaController.addClassIfNotExists('SuperCar', {
      engine: { type: 'String' },
      doors: { type: 'Number' },
      price: { type: 'String' },
      mileage: { type: 'Number' },
      gears: { type: 'Array' }
    });

    await new Parse.Object('SuperCar').save({
      engine: 'petrol',
      doors: 3,
      price: '£7500',
      mileage: 0,
      gears: ['1', '2', '3', '4']
    });

    await new Parse.Object('SuperCar').save({
      engine: 'petrol',
      doors: 3,
      price: '£7500',
      mileage: 10000,
      gears: ['1', '2', '3', '4', '5']
    });

    await Promise.all([
      parseGraphQLServer.parseGraphQLController.cacheController.graphQL.clear(),
      parseGraphQLServer.parseGraphQLSchema.schemaCache.clear(),
    ]);

    Parse.Cloud.define('arrayOfSuperCar', async () => {
      const superCars = await new Parse.Query('SuperCar').find({useMasterKey: true})
      return superCars
    });
    const result = await apolloClient.query({
      query: gql`
      query FindSuperCar {
        arrayOfSuperCar {
          objectId
          objectId
          gears {
            ... on Element {
              value
            }
          }
        }
      }
    `,
    })
    expect(result.data.superCars.gears[2].value).toEqual('3');
  });`

Would you be interested in opening a PR with this failing test case and helping us to solve this issue?

#5

I created a PR for which includes the test, inital test that shows the bug by axelhildingson · Pull Request #7506 · parse-community/parse-server · GitHub</titl
