What happens?:
We're getting validation errors from our own testing with overridden experiment users, see example from Growth event validation logstash dashboard.
What should have happened instead?:
No events from these users should be sent. This is because ReviseToneInteractionLogger does not behave as the TestKitchen JS client which drops traffic from overridden users.
Once T415277 is resolved, GE can update its client to the experiment pre-configured which will take care of this.
