automatically generated code is diffrent from API, AppSync and DataStore

[bjg2327]

Describe the bug

I have generated a model named EventNews.
But I'm getting an error in getList.
There is no problem with AWS AppSync Console and DataStore.

an error

Got failed result with GraphQL service returned a successful response containing errors: [Amplify.GraphQLError(messagee: "Validation error of type FieldUndefined: 'listEventNewss'\ in type 'Query'\ is undefined @'listEventNewss'", locations: Optional([Amplify.GraphQLError.Location(line: 2, column: 3)]), path: nil, extensions: nil)]

This problem seems to be due to the naming process

listEventNewss

// Code that causes an error
Amplify.API.query(request: .paginatedList(EventNews.self, limit: 100)
    .resultPublisher
    .sink { if case let .failure(error) = $0 { print("Got failed event with error \(error)") } }
    receiveValue: { result in
        switch result {
            case .success
            ...
           case .failure(let error):
               print("Got failed result with \(error.errorDescription)") // <-- Here
   }

// No problem with DataStore
Amplify.DataStore.query(EventNews.self)
   ...

// AWS AppSync Console
query MyQuery {
  listEventNews {
    items {
      id
    }
  }
}

Steps To Reproduce

1. Generate Model 'EventNews'

2. do Query
Amplify.API.query(request: .paginatedList(EventNews.self, limit: 100)

Expected behavior

Getting the list successfully

Thanks for opening this, @bjg2327. We will take a look and get back to you.

Hi @bjg2327, could you provide us with the contents of your amplify/cli.json file from the amplify cli project? specifically improvepluralization, useexperimentalpipelinedtransformer, and transformerversion.

// Example
{
  "features": {
    "graphqltransformer": {
      "addmissingownerfields": true,
      "improvepluralization": false, // this value
      "validatetypenamereservedwords": true,
      "useexperimentalpipelinedtransformer": true, // this value
      "enableiterativegsiupdates": true,
      "secondarykeyasgsi": true,
      "skipoverridemutationinputtypes": true,
      "transformerversion": 2, // this value
      "suppressschemamigrationprompt": true,
      "securityenhancementnotification": false,
      "showfieldauthnotification": false
    },
...

There seems to be some regression happening, which i was able to reproduce here #1707 (comment)

Once this aws-amplify/amplify-codegen#255 is released, you can upgrade to the latest CLI and it will generate those fields for you automatically.

Hi @lawmicha
Code Here

"features": {
    "addmissingownerfields": true,
    "improvepluralization": false,
    "validatetypenamereservedwords": true,
    "useexperimentalpipelinedtransformer": true, 
    "enableiterativegsiupdates": true,
    "secondarykeyasgsi": true,
    "skipoverridemutationinputtypes": true,
    "transformerversion": 2,
    "suppressschemamigrationprompt": true,
    "securityenhancementnotification": false,
    "showfieldauthnotification": false
}
...

Once this aws-amplify/amplify-codegen#255 is released, you can upgrade to the latest CLI and it will generate those fields for you automatically.

Thank you for answering

Please use Amplify CLI 12.4.0 or greater to get the fix for the pluralization issue
