Inline fragment

[dcucchietti]

Hi,

I'm trying to flatten fragments in my response models, but I'm encountering an issue where the fragments are wrapped in a nested object.

Here’s the GraphQL query I’m using:

fragment AuthenticationFragment on SessionInfo {
  role
  sessionGUID
  token
}

mutation loginAsGuest {
    login(
        lang: { key: "FRA" }
    ) {
        ...AuthenticationFragment
    }
}

The expected response (from a GraphQL client like Postman) is:

{
    "data": {
        "login": {
            "role": "XXX",
            "sessionGUID": "XXX",
            "token": "XXXX"
        }
    }
}

However, when using the Apollo Java Client, the response looks like this:

{
    "login": {
      "__typename": "SessionInfo",
      "authenticationFragment": {
        "role": {
          "rawValue": "XXX"
        },
        "sessionGUID": "XXX",
        "token": "XXX"
      }
    }
  }

As you can see, the fields of the AuthenticationFragment are nested inside the authenticationFragment object.

How can I remove the authenticationFragment wrapper and directly flatten the fields (role, sessionGUID, token) into the login object?

I have tried enabling the flattenModels option in the plugin configuration, but it didn’t work as expected.

Any missing configuration ?
Below my configuration :
