Describe the bug

I tried to run a delete mutation on AWS AppSync to test if my API works, it seems that I can create a record with @auth with the tokens but it failed to delete the object I just created. I confirmed the owner of the record is the same as the one who is trying to delete the same record but it returned "Not Authorized to access deleteBlog on type Mutation" which is very strange.

Provided my schema in Reproduction steps section. Is there any misconfiguration I had made? Thank you.

Expected behavior

The mutation should allow owners of the record to delete their own records.

Reproduction steps

1. Create the GraphQL schema as below:
   type Blog @model @auth(rules: [{ allow: public, operations: [read] }, { allow: owner, operations: [create, update, delete] }]) {
   id: ID!
   name: String!
   summary: String
   imgPath: String
   posts: [Post] @hasmany @auth(rules: [{ allow: public, operations: [read] }])
   }

I can tell it is a bug since I looked at the schema at AppSync, under type Mutation, the label @aws_cognito_user_pools should be added given the schema I pushed. (I did not provide my entire schema in my post). Interestingly, if I define another table like this:

type Project @model @auth(rules: [{ allow: owner, operations: [read, create, update, delete] }]) {
  id: ID!
  name: String!
  description: String!
  completion: Float
  status: Boolean
  user: User @belongsTo
}

AppSync is able to generate the schema correctly. May I know is that relevant?
