JSONAPISource Serialization Problem

[gang-qiu]

Hello there, Thanks for this amazing library! I have been following the setup instructions and I was able to set up my schema, load it into Memory and JSONAPI sources, query my backend and it is responding with standard json-api format. However, I was quite surprised to see that the result of the query is just the raw json-api body, and it appears the data isn't being parsed. I am wondering if I have to explicitly pass in a serializer to my JsonApiSources configurations?

const localCacheSource = new MemorySource({
      schema,
      name: 'localCache'
    })
    setLocalCache(localCacheSource)

    // set up api service
    const apiServiceSource = new JSONAPISource({
      schema,
      name: 'apiService',
      host: baseUrl,
      defaultFetchSettings: {
        headers: {
          Authorization: `Bearer ${authToken}`
        }
      },

      // pluralize resource names in urls properly. ie, entity model => entities (defaults to entitys)
      // https://github.com/orbitjs/orbit/issues/885#issuecomment-1065926542
      serializerSettingsFor: buildSerializerSettingsFor({
        sharedSettings: {
          inflectors: {
            pluralize: buildInflector(
              { entity: 'entities'},
              (input) => `${input}s`
            ),
            singularize: buildInflector(
              { entities: 'entity'},
              (arg) => arg.substring(0, arg.length - 1)
            )
          }
        }
      })
    })
    setApiService(apiServiceSource)

    // set up coordinator
    const coordinator = new Coordinator({
      sources: [localCacheSource, apiServiceSource]
    })

    coordinator.addStrategy(
      new RequestStrategy({
        source: 'localCache',
        on: 'beforeQuery',
        target: 'apiService',
        action: 'query',
        blocking: true,
      })
    )

    // Update the apiSource server whenever the memory source is updated
    coordinator.addStrategy(
      new RequestStrategy({
        source: 'localCache',
        on: 'beforeUpdate',
        target: 'apiService',
        action: 'update',
        blocking: false,
      })
    )
    await coordinator.activate()

   apiServiceSource.query(q => q.findRelatedRecords(
        {type: 'entity', id: '1'}, 'documents')
      ).then(data => console.log(data))

// in the console i see the serialized json response

{
  "data": [
    {
      "id": "1",
      "type": "document",
      "attributes": {
        "name": "test document"
      },
      "relationships": {
        "documentType": {
          "data": {
            "id": "1",
            "type": "documentType"
          }
        }
      }
    }
  ],
  "included": [
    {
      "id": "1",
      "type": "documentType",
      "attributes": {
        "name": "Certificate of Incorporation"
      }
    }
  ]
}

I expect to see...

{name: 'test document', documentType: {id: "1", name: "Certificate of Incorporation"}}

Thank you in advance
