I’m also having this same problem. When the asset in question is a blueprint, the cast always fails for me. I spent a lot of time trying to find a solution but I didn’t find one.
I also tried using this node
but I get the log
LogScript: Warning: Script Msg: Property 'NewVar' on '/Game/Widgets/SkillTree/NewBlueprint.NewBlueprint' (Blueprint) was missing
If anyone can help
