Describe the bug

This schema is generating an autogenerated pipeline resolver that I'm unable to override using the amplify/backend/api/myapi/override.ts

schema.graphql

type User
  @model() {
  id: ID!
  firstname: String!
  lastname: String
  Children: [Child]
    @hasMany(indexName: "byUser", fields: ["id"])
}

type Child
  @model() {
  id: ID!
  firstname: String!
  lastname: String!
  userID: ID
    @index(name: "byUser")
  User: User
}

It seems like the key User.Children autogenerate, a resolver that I'm unable to override.

Override.ts

  const getChild = resources.models['Child'];
  const getChild2 = resources.models['User'];

  console.log(getChild)
  const getChildResolvers =
    getChild.resolvers['queryGetChildResolver'].pipelineConfig['functions'];
  getChild.resolvers['queryGetChildResolver'].pipelineConfig = {
    functions: [
      function_1,
      function_2,
      function_3,
      ...getChildResolvers,
    ],
  };

When I log the following, I'm unable to see the autogenerated pipeline resolver in the data structure:

const getChild = resources.models['Child'];
or 
const getChild = resources.models['User'];

On the other hand, when I look at the AWS UI I'm able to see the autogenerated function

---

Expected behavior

Being able to override the pipeline resolver that was automatically generated by amplify

Reproduction steps

1. Add this schema
2. Push it to amplify
3. Create an override.ts file and try to override the autogenerated function

Hey @jguipi, 👋 thanks for raising this! I'm going to transfer this over to our API repository for better assistance 🙂. But refer to https://docs.amplify.aws/gen1/react/build-a-backend/graphqlapi/custom-business-logic/#override-amplify-generated-resolvers providing information on overriding Amplify generated resolvers.

As extra detail, I already copied the autogenerated resolver into the right path

From: amplify/backend/api/DevApi/build/resolvers To : amplify/backend/api/DevApi/build/tsconfig.resource.json

Is it normal that the file that were autogenerated are not following the naming convention mentioned here. The current files name are presented in the screenshot

Hi @jguipi, Thanks for bringing this up. To override the resolvers, you need to copy the autogenerated resolver from amplify/backend/api/<resource_name>/build/resolvers/ to amplify/backend/api/<resource_name>/resolvers/. The naming convention in the screenshot is expected for relationship tables. Please let us know if you still encounter any issues.

That was already done, but when I try to add the code in the override.ts to override the pipeline resolver that fonction is not there.

As shown above, I was not able to found the function in either of those model:

const getChildModel= resources.models['Child'];
const getUserModel = resources.models['User'];

console.log(getChildModel)
console.log(getUserModel)

getChildModel return

getUserModel return

There is no mention of that autogenerated function
