Assertion failed: ResultString.Num() == 3 [File:D:\UnrealEngine\SourceGit\Engine\Source\Editor\AnimGraph\Private\AnimGraphNode_SkeletalControlBase.cpp] [Line: 298]

When I click “Transform (Modify) Bone” node in animation blueprint editor, this assert occured.

I have debug and found that the “Scale” pin’s “DefaultValue” was “Empty”:

Hi LewUniverse,

I was able to reproduce this and have entered the following bug report: JIRA [UE-11292]. Should this be addressed in a future build of the engine, an update will be added to this post.

Thank you for your feedback.
