Blueprint::BlueprintType does not seem to be accessible in Python. How would one access it?
Found a work around with some help. BlueprintType isn’t accessible but you can test the class type:
blueprint = unreal.EditorAssetLibrary.load_blueprint_class(path_to_bp)
if unreal.get_type_from_class(blueprint) == unreal.BlueprintFunctionLibrary:
unreal.log("Found blueprint function library object")
