Can't call BehaviorTree Task

The task of the behavior tree
I made it with another module file
Unable to call the task from the editor side
What should I do now?

Hello! Can you share more details and full error text? Are you using CPP or BP? If CPP, can you provide .h for this task? Also, check build.cs for module dependencies…

Can you picture error message or attach log? Also check this lines in Build.cs

using System.IO;

...

		// ... add public include paths required here ...
		PublicIncludePaths.AddRange(new string[] { Path.Combine(ModuleDirectory, "Public") });

		// ... add other private include paths required here ...
		PrivateIncludePaths.AddRange(new string[] { Path.Combine(ModuleDirectory, "Private") });

It is solved
It was because I put _ in the name of the class.
IncludePath is not in Build.cs
Will it be used for something?

It just declare this folders as Public and Private for module dependencies. How can it be that _ just breaks compilation )) I always was thinking that underscore is fine )) But of course it dependes on compiler ))
