{"message":"GenServer #PID<0.3385.0> terminating\n** (FunctionClauseError) no function clause matching in MindwendelWeb.IdeaLive.CardComponent.handle_event/3\n (mindwendel 0.2.9) lib/mindwendel_web/live/idea_live/card_component.ex:9

The card component does not have a validate method and its also not called. Currently unclear, how this method call is triggered.
