@anonymous_user_b5a3220c, judge from the icon in your screenshot, I think you’re using the buildin “Blueprint Script Component” which is not the same as “Lua” Script Component came from Lua Script Plugin.
@, is there any good approach to bind/export UStructs automatically? (As there’s only limited UStructs supported hardcoded in ScriptPlugin, so any function signature using UStructs not supported will not be binded.)
