Call Event in Blueprint Service

Hey,
currently I have a bot that uses the behavior tree to patrol along given waypoints. I want him to run at the player if the player picks up an object. I have a service attached to a sequence node wich checks every tick if the player is in range. My idea was to add an event “Player steals”. There I would check if the bot has a line of sight and if yes set the state of my bot to “attack”. My problem now is that I don’t know how to call that event. For normal blueprints I would create an object variable and assign the blueprint that has the event in and than call it but for services this does not seem to work. Any hints in what I’m doing wrong or other suggestion on how to communicate with the blueprint service?
Thanks in advance

I am working with the exact same situation :frowning: Did you ever find a solution to this? Thanks
