amplify-js: DataStore - Sync error, subscription failed Connection failed: {"errors":[{"message":"Validation error of type FieldUndefined: Field 'blogDemoPostsId' in type 'PostDemo' is undefined @ 'onCreatePostDemo/blogDemoPostsId'"}]}

Describe the bug When I try to query/observe and save an object into the datastore I get following error:

[WARN] 55:26.322 DataStore - Sync error, subscription failed Connection failed: {"errors":[{"message":"Validation error of type FieldUndefined: Field 'blogDemoPostsId' in type 'PostDemo' is undefined @ 'onCreatePostDemo/blogDemoPostsId'"}]}

I get this error when I interact with DataStore with this snippet:

const testDataStore = (username: string) => {
  DataStore.query(BlogDemo)
    .then((data) => {
      console.log(data);
      DataStore.observe(BlogDemo).subscribe((event) => {
        console.log("=======SUB======");
        console.log(event);
      });
      let blog = new BlogDemo({
        name: "testBlog",
        posts: [],
        editors: [username],
      });
      console.log("save blog post");
      DataStore.save(blog);
    })
    .catch((err) => console.log(err));
};

To Reproduce Steps to reproduce the behavior:

  • Initialised a new project with Expo SDK 37.0.0 and Amplify Cli 4.18.0 and aws-amplify 3.0.7 and @aws-amplify/pubsub 3.0.7.
  • added api, and auth.
  • used provided schema for Blog, Posts and Comment.
  • amplify codegen I get the error (argument must be a string)
  • fixed the model and pushed changes with amplify push
  • ran amplify codegen models that gives me an error saying that I can’t use keyName in connection.
  • removed all connection and keys from the schema obtaining the following schema:
type BlogDemo @model @auth(rules: [{ allow: owner, ownerField: "editors" }]) {
  id: ID!
  name: String!
  posts: [PostDemo] @connection
  editors: [String]!
}

type PostDemo @model @auth(rules: [{ allow: owner, ownerField: "editors" }]) {
  id: ID!
  title: String!
  blog: BlogDemo @connection
  comments: [CommentDemo] @connection
  editors: [String]!
}

type CommentDemo
  @model
  @auth(rules: [{ allow: owner, ownerField: "editors" }]) {
  id: ID!
  post: PostDemo @connection
  content: String!
  editors: [String]!
}

I added owners attributes as an Array su support multiple oweners.

Expected behavior DataStore works without any error. And I can save/query and subscribe to Models.
