Accessed none when running User Created BP in another Widget BP?

As the title is stating, I have two blueprints. One is the main lobby blueprint, the other is a character preview blueprint called “WBP Preview Char”. When I drop the Preview Char blueprint inside of my lobby blueprint via User Created selection on the left, I get a wall of errors that it can’t access any of the nodes on the Preview Char BP. I understand that I normally need to have an isValid? node on the blueprints when you get an accessed none error, but I’m not going that route since I drag and dropped the Preview Char BP directly on my lobby BP…How did I get my lobby BP to access it?? Thanks, everyone!
