AWS Amplify API 错误 - 字段不是 Int 类型

Question

I'm trying to push my AWS Amplify API schema/create the resource but it errors out saying:

✖ An error occurred when pushing the resources to the cloud

managerId field is not of type Int

The error goes away if I change managerId to an Int on the Writer type but I don't want to do that. It should be an ID. Any idea what's wrong here?

schema.graphql

type Writer implements Person 
  @model
  @searchable
  @key(name: "byManager", fields: ["managerId", "hourlyPay"])
  @auth(rules: [
    {allow: groups, groups: ["Admin"]},
    {allow: public, provider: iam, operations: [read]}
  ])
{
  id: ID!
  managerId: ID!
  name: String!
  hourlyPay: Float!
  manager: Manager! @connection(fields: ["managerId"])
}

type Manager implements Person 
  @model
  @searchable
  @auth(rules: [
    {allow: groups, groups: ["Admin"]},
    {allow: public, provider: iam, operations: [read]}
  ])
{
  id: ID!
  name: String!
  department: String
  writers: [Writer!]! @connection(keyName: "byManager", fields: ["id"])
}

Thanks!

I had the same issue in an Android project I was working on.

I fixed it by placing the next code in a file I created under app/src/main/graphql (I had to create the folder graphql).

/app/src/main/graphql/aws-directives.graphql

directive @connection(name: String, keyField: String, sortField: String, limit: Int) on FIELD_DEFINITION

Then, instead of using @key I only used the directive @connection like this

type Comment @model {
   id: ID!
   text: String!
   postId: Post @connection(name: "commentsByPost")
}


type Post @model {
   id: ID!
   comments: [Comment] @connection(name: "commentsByPost")
}

Finally when you create comments you have to pass the postId. If you do a query to list the Posts and its comments you will get the comments associated with each post correctly.
