AI character does not move

I am following tutorial [Behavior Tree Tutorial][1]

When I completed all steps and tried to run it - the AI character does not move at all. Moreover in the simulating mode it marked two decorators with red.
What might be the problem?

The screenshot you’ve shown says you don’t have the TargetToFollow set. Make sure you set it and retry.



Wow, indeed. I did not set in desiredObjectType one element as pawn
