Issue 1

when doing

let request = GraphQLRequest<Post>.list(Post.self)

try await Amplify.API.query(request: request)

i can’t to get the comments details

Post(id: "FC51010E-517E-40F4-AE59-A98317298348", title: "Post 1", description: nil, comments: Optional(Amplify.List<MyFirstApp.Comment>), userID: "c273f24c-7c22-42bc-9f91-102b42646347", createdAt: Optional(Amplify.Temporal.DateTime(foundationDate: 2023-03-09 08:48:25 +0000)), updatedAt: Optional(Amplify.Temporal.DateTime(foundationDate: 2023-03-09 08:48:25 +0000))), MyFirstApp.Post(id: "0ED9558E-A4D8-447E-BF93-1047F196BE66", title: "Post 2", description: Optional("description"), comments: Optional(Amplify.List<MyFirstApp.Comment>), userID: "c273f24c-7c22-42bc-9f91-102b42646347", createdAt: Optional(Amplify.Temporal.DateTime(foundationDate: 2023-03-09 10:25:51 +0000)), updatedAt: Optional(Amplify.Temporal.DateTime(foundationDate: 2023-03-09 10:25:51 +0000)))]

Issue 2

Follow the link https://docs.amplify.aws/lib/graphqlapi/advanced-workflows/q/platform/ios/#nested-data

Create own GraphQLRequest

extension GraphQLRequest {

    static func getPostId(byId id: String) -> GraphQLRequest<Post> {
        let document = """
        query getPost($id: ID!) {
          getPost(id: $id) {
            id
          }
        }
        """
        return GraphQLRequest<Post>(
            document: document,
            variables: ["id": id],
            responseType: Post.self,
            decodePath: "getPost"
        )
    }
}

when doing

try await Amplify.API.query(request: .getPostId(byId: id))

then return error

Failed to create graphql GraphQLResponseError<Post>: Failed to decode GraphQL response to the `ResponseType` Post
Recovery suggestion: Failed to transform to `ResponseType`.
Take a look at the `RawGraphQLResponse` and underlying error to see where it failed to decode.
Caused by:
APIError: keyNotFound key CodingKeys(stringValue: "title", intValue: nil)
Caused by:
keyNotFound(CodingKeys(stringValue: "title", intValue: nil), Swift.DecodingError.Context(codingPath: [], debugDescription: "No value associated with key CodingKeys(stringValue: \"title\", intValue: nil) (\"title\").", underlyingError: nil))

When i run at the AWS AppSync Queries Console i can get back the nested detail and created my custom graphql

Steps To Reproduce

amplify init
amplify add auth (cognito)
amplify add api (with conflict detection-> auto merge)
amplify add storage
amplify codegen models
amplify push

Expected behavior

Issue 1
