Describe the bug

After running amplify codgen to produce typescript code for a graphql API, the queries.ts file does not compile if the GraphQL API has a query function with no parameters.

Specifically the queries.ts code will have code like so that has a ts error:

` as GeneratedQuery<
  APITypes.GetProductsQueryVariables,
  APITypes.GetProductsQuery

The error is './graphql-schema' has no exported member APITypes.GetProductsQueryVariables

If you check the graphql-schema.ts file, you'll see there is no APITypes.GetProductsQueryVariables type defined. I assume because this function has no parameters and therefore there are no input variables to define.

Expected behavior

amplify codegen should produce syntactically correct queries.ts file.

Reproduction steps

1. Make sure you have a function in your graphql API that does not have any parameters, e.g:

type Query { 
     getProducts: [Product!] @function(name: 'MyLambda-${env}')
}

2. Configure your .graphqlconfig.yml file to produce typescript graphql schema code like so:

projects:
   myGraphQLSchema:
    schemaPath: amplify/backend/api/MyAPI/build/schema.graphql
    includes:
      - frontend/projects/shared/graphql/**/*.graphql
    excludes:
      - ./amplify/**
    extensions:
      amplify:
        codeGenTarget: typescript
        generatedFileName: /my-graphql/graphql-schema.ts
        docsFilePath: my-graphql/
        region: us-east-1
        apiId: null
        maxDepth: 7
extensions:
  amplify:
     version: 3

3. Run amplify codegen and examine the resulting queries.ts file

Hey @hisham, Thank you for bringing this matter to our attention. Following the instructions outlined in the issue, we observed that amplify codegen is not generating the code for custom queries as expected. Therefore, we're categorizing this as a bug for the team to conduct further investigation.

Here's a snippet of the schema and .graphqlconfig.yml used:

Schema:

input AMPLIFY {
  globalAuthRule: AuthRule = { allow: public }
} # FOR TESTING ONLY!
type Todo @model {
  id: ID!
  name: String!
  description: String
}

type Query {
  getTodos: [Todo!] @function(name: "test-${env}")
}

.graphqlconfig.yml:

projects:
  "1960":
    schemaPath: amplify/backend/api/1960/build/schema.graphql
    includes:
      - src/graphql/**/*.ts
    excludes:
      - ./amplify/**
    extensions:
      amplify:
        codeGenTarget: typescript
        generatedFileName: src/graphql-schema.ts
        docsFilePath: src/graphql
extensions:
  amplify:
    version: 3

Upon running amplify codegen, the expected code generation did not occur.

looks like this has been fixed in the latest release btw.

This is still happening on a mac on release 12.13.0
