StateTreeAiComponent not executing

I am trying to use the new StateTree AI Component, but cannot get it to run.
I created a Tree and a Pawn with an State Tree AI-Component. But when I Play in Editor, the Tree does not execute. Neither do Task run nor is the OnStateTreeRunStatusChanged-Callback called.
I tried attaching the TreeComponent to a custom AI Controller, but that did not trigger anything either.

Where do I have to attach the StateTree AI Component and what are other requirements to get it to run?

Not sure what your use-case is here, but I’ve had similar problems.

Try adding a StateTree component to your actor / pawn (not StateTreeAI) and then make a StateTree for it by using StateTreeComponentShema (not StateTreeAIComponentShema). Worked for me.
