Invalid Controller received (predefined task/behavior tree)

I am getting this error when trying to run the predefined tasks in a behavior tree.

i did my own task and it does work fine

What am I doing wrong in the first case?
I want to use the predefined tasks.

Thank you so much!!

Sorry if this is a dumb question, but are you sure that your Move To Actor is not something you’ve added already? That log format doesn’t look like Epic’s kind of thing, and I don’t have anything like “BTT_AIMoveToActor” in my tree anywhere. Epic’s tasks all start with BTTask.

Yes, I am quite sure that this task is supplied by unreal 5.0.3…
I did not write the following code

And that is not the only task that has given me the same problem. I tried a few others and had identical results.

Really unreal 5.0.3. has a lot of default tasks.

There are 55, but mine are only about 10 more or less.

Thank you very much!!
