Unable to get AWS AppConfig configuration file with boto3_client passed to AppConfigStore

[Rogalek]

Hello

When I am trying to run feature_flags.get_enabled_features() I am getting this error:

[DEBUG]	2024-11-04T14:53:42.210Z	cab62e2e-1609-4121-a058-6fd3eec9c7e2	Failed to fetch feature flags from store, returning empty list, reason=Unable to get AWS AppConfig configuration file

I am trying to run this code:

    app_config = AppConfigStore(
        environment=ENV,
        application=APPCONFIG_APPLICATION_NAME,
        name=configuration_profile,
        sdk_config=Config(region_name=APPCONFIG_REGION),
        boto3_client=restricted_client(service_name="appconfig", region_name=APPCONFIG_REGION),
    )
    feature_flags = FeatureFlags(store=app_config, logger=logger)
    features = feature_flags.get_enabled_features(context=ctx)

When I use this restricted_client (its a my own class which inherits from boto3) for example to:
restricted_client.list_configuration_profiles(ApplicationId=APPCONFIG_APPLICATION_ID) - It is working perfectly but I cannot evaluate flags.

Can someone help me? What I do wrong?

Hi @Rogalek! I finally found some time to inspect it. The problem is that you are using an instance of appconfig boto3.client, when in reality you need to use appconfigdata because this is the client that can communicate with the AppConfig Data Plane and query its values ​​stored in your application and environment. We mention that in our documentation.

restricted_client(service_name="appconfig", region_name=APPCONFIG_REGION)

should be

restricted_client(service_name="appconfigdata", region_name=APPCONFIG_REGION)

Please let me know if this works.

thank you - this is it - I missed that.
