Why is different code generated with the same swagger file? I give an example below.

The project was like this from the beginning and everything worked well.

//Login and password authorization
  ///@param username Name
  ///@param password password
  Future<chopper.Response<Object>> loginJsonPost({
    required String? username,
    required String? password,
  }) {
    return _loginJsonPost(username: username, password: password);
  }

///Login and password authorization
  ///@param username Name
  ///@param password password
  @Post(
    path: '/login.json',
    optionalBody: true,
  )
  Future<chopper.Response<Object>> _loginJsonPost({
    @Query('username') required String? username,
    @Query('password') required String? password,
  });

After regenerating the chopper code, it became like this and now an error occurs when trying to log in
Error:type 'Response' is not a subtype of type 'Response<LoginJsonPost$Response>' in type cast:

Future<chopper.Response<LoginJsonPost$Response>> loginJsonPost({
    required String? username,
    required String? password,
  }) {
    generatedMapping.putIfAbsent(
        LoginJsonPost$Response, () => LoginJsonPost$Response.fromJsonFactory);

    return _loginJsonPost(username: username, password: password);
  }

  ///Login and password authorization
  ///@param username Name
  ///@param password password
  @Post(
    path: '/login.json',
    optionalBody: true,
  )
  Future<chopper.Response<LoginJsonPost$Response>> _loginJsonPost({
    @Query('username') required String? username,
    @Query('password') required String? password,
  });

However, the swagger code for this method has not changed.
Please tell me why this is happening, what needs to be done to return to the previous state?

Hello!

Old version returned Object as a return type. New version supports responses as models. In your case it's LoginJsonPost$Response. Previously, you had Object and needed to parse it manually.

Regarding your error (Response<LoginJsonPost$Response>' in type cast) I need more details. On which line it's occurs?
