I’m following the Unreal Engine Online Learning Course Introduction to AI with Blueprints. In the module on testing the behavior tree the instructor shows us how to visualize the tree in the debugger, but it does not show for me. There is no output for AI or Perception either, but the behavior tree is working when playing the game. Relevant video in the course is here.

This bug has been reported before in another post here.

In the AIController event graph I was calling Run Behavior Tree from Event On Posses and the BTAsset was already set to the correct asset reference. I set it to None then compiled and saved the blueprint, then set it back to the asset it was originally set to, compiled and saved. This fixed the issue, but there’s definitely a bug in the engine source for this version.
