Describe the bug

A multi-level item in selectionSet is not received.

Expected behavior

Expected to receive data for any level of nested query.

Reproduction steps

• Declare schema as following:

import { a } from "@aws-amplify/backend";

const schema = a.schema({
  CommunityPost: a.model({
    id: a.id().required(),
    poll: a.hasOne("CommunityPoll"),
  }),

  CommunityPoll: a.model({
    id: a.id().required(),
    question: a.string().required(),
    answers: a.hasMany("CommunityPollAnswer").arrayRequired().valueRequired(),
  }),

  CommunityPollAnswer: a.model({
    id: a.id().required(),
    answer: a.string().required(),
    votes: a.hasMany("CommunityPollVote").arrayRequired().valueRequired(),
  }),

  CommunityPollVote: a.model({ id: a.id().required() }),
});

• Try to get data using:

amplifyClient.models.CommunityPost.get(
    { id: 'post id' },
    {
      selectionSet: [
        "id",
        "poll.id",
        "poll.question",
        "poll.answers.id",
        "poll.answers.answer",
        "poll.answers.votes.id",
      ],
    }
  );

• CommunityPost is received.
• poll properties are received.
• poll.answers properties are received, except for poll.answers.votes

Testing directly through AppSync, with query:

query MyQuery {
  listCommunityPosts {
    items {
      id
      poll {
        question
        answers {
          items {
            answer
            votes {
              items {
                id
              }
            }
          }
        }
      }
    }
  }
}

Following data is returned:

{
  "data": {
    "listCommunityPosts": {
      "items": [
        {
          "id": "2",
          "poll": null
        },
        {
          "id": "1",
          "poll": {
            "question": "Is this a good question for showing in issue?",
            "answers": {
              "items": [
                { "answer": "Yes", "votes": { "items": [] } },
                { "answer": "No",  "votes": { "items": [ { "id": "f0396484-e3c8-4fbc-87cb-1811bad7b4af" } ]  }
                }
              ]
            }
          }
        }
      ]
    }
  }
}

Hi @erickriva 👋 thanks for raising this issue. Can you inspect the network request that is made when using the client?

Is the shape of the graphql request the same as the one you tried in the AppSync console?

[erickriva]

I think I may have confused up things (sorry, it was almost midnight 🥱), but seems there's a bug here still.

Request:

{
  "query": "query ($id: ID!) {\n  getCommunityPost(id: $id) {\n    id\n      poll {\n      id\n      question\n      answers {\n        items {\n          votes {\n            items {\n              id\n            }\n          }\n        }\n      }\n    }\n  }\n}\n",
  "variables": {
    "id": "1"
  }
}

Response:

{
  "data": {
    "getCommunityPost": {
      "id": "1",
      "poll": {
        "id": "1",
        "question": "Is this a good question for showing in issue?",
        "answers": {
          "items": [
            {
              "votes": {
                "items": []
              }
            },
            {
              "votes": {
                "items": [
                  {
                    "id": "f0396484-e3c8-4fbc-87cb-1811bad7b4af"
                  }
                ]
              }
            }
          ]
        }
      }
    }
  }
}

They seems to match between them, but not with my code: selectionSet: [ "id", "poll.id", "poll.question", "poll.answers.id", "poll.answers.answer", "poll.answers.votes.id" ]

answers.id and answers.answer aren't present in the request, so no response too. But answers.votes.id is present.

@chrisbonifacio I've been trying to modify the lib's code for the last days and I think I have solved the issue. Don't know about performance yet. I will open a PR soon.

[erickriva]

In the case this PR is approved, I'll send another to fix this issue, at least the execution part of it. Maybe I can fix TS too.

[chrisbonifacio]

Hey @erickriva thank you for looking into this and submitting a PR! I will bring it to the team's attention.

[erickriva]

PR #12701 was merged, released in 6.0.9, and this problem was solved.
Thank you @chrisbonifacio!

[chrisbonifacio]

@erickriva thank YOU, sir! Excellent work 🙏
