Here there's no check that featureFlagSelector.KeyFilter and featureFlagSelector.LabelFilter are not null. They might be since featureFlagSelector could be initialized with SnapshotName

IConfigurationClientManager.GetEndpointForClient can return null if it doesn't find the client, but everywhere it's used return value is never checked for null (here's an example)
