Identity overrides don't work in offline local evaluation mode

Comece em flagsmith/flagsmith.py, no caminho de carregamento do handler offline por volta da linha 117 e no caminho de atualização da API por volta da linha 273; rastreie como identity_overrides são representados no arquivo local. Verifique se a avaliação local offline aplica o override para o identificador 146433, preservando o comportamento normal do estado das features, e adicione ou execute cobertura de regressão para esse caso.

I'm using version 3.8.0 and have identity overrides enabled for my environment.

I'm using a copy of a config for local development and initialize Flagsmith as follows:

local_file_handler = LocalFileHandler(
    environment_document_path=f"./feature_flags_configuration.local.json"
)
flagsmith = Flagsmith(
    environment_key=settings.FLAGSMITH_API_KEY,
    enable_local_evaluation=True,
    offline_handler=local_file_handler,
    offline_mode=True,
)

I have following settings on my config:

  "feature_states": [
    {
      "feature": {
        "id": 103972,
        "name": "ipqs_geo_ip",
        "type": "STANDARD"
      },
      "enabled": true,
      "django_id": 576867,
      "feature_segment": null,
      "featurestate_uuid": "04dcc7d5-b387-4668-8264-d30a2da2e111",
      "feature_state_value": null,
      "multivariate_feature_state_values": []
    }
  ],
  "identity_overrides": [
    {
      "identifier": "146433",
      "environment_api_key": ...,
      "created_date": "2024-08-26T17:45:31.959128Z",
      "identity_features": [
        {
          "feature": {
            "id": 103972,
            "name": "ipqs_geo_ip",
            "type": "STANDARD"
          },
          "enabled": false,
          "django_id": null,
          "feature_segment": null,
          "featurestate_uuid": "964dd1e9-b34a-4bf7-9984-937abbba3f0e",
          "feature_state_value": null,
          "multivariate_feature_state_values": []
        }
      ],
      "identity_traits": [],
      "identity_uuid": "8fd6de03-b834-41d2-b5ec-7076d00e6cd3",
      "django_id": null,
      "composite_key": "cfWNJQwEQkcAiKxSPFL2rv_146433"
    }
  ],

However, identity overrides are ignored unless I disable offline mode.

The root cause must be that it is updated only here when API request is made and are not loaded from offline handler here.

In production, I'm also using the local file as a fallback for the case when Flagsmith is unavailable during app start, so it might become a problem in production in rare cases.
