HI, Where is Function "get user widget object" in UE4.17.2

Hi. I’m having the same problem with the same tutorial, but solution above isn’t working anymore. Inside the function casting to widget class always fails. More specifically, “Get user widget object” isn’t working and is returning null. The “Get object name” returns “Nothing” and IsValid check returns “Fail”.
But everything works if called from event graph. So as far as I understand you can’t use GetUserWidgetObject in the Construction Script at all, not even inside a function, it just doesn’t return anything.
