DOTS Visual Scripting Bug?

Hello. If you use a custom node in Visual Scripting and update the program for that node while the Visual Script window is open, you will get an error similar to the following.

NullReferenceException: Object reference not set to an instance of an object
DotsStencil.SetComponentNodeModel.get_Title () (at Library/PackageCache/com.unity.visualscripting.entities@0.3.1-preview.2/Editor/NodeModels/Flow/ECS/SetComponentNodeModel.cs:1

The lines between the nodes disappear, but when you play the game it runs correctly.
Somebody, help me. Thank you in advance.

its experimental right now

Thank you for your reply.
I will use it as it is until it is no longer experimental!
