Windows 10: Windows Update API gives empty download URL for windows 10 cumulative updates

I am using a C++ program which uses WUAPI to scan for updates against Microsoft Update Catalog. Things were working fine for quite a while, but in recent days, I am seeing certain KB articles are not providing download URL. These are especially cumulative updates.I have verified Microsoft Update Catalog for same KB article, but there I can find the updates available and able to download from there. Please help on this.Client operating system: Windows 10 version 21H1 OS Build 19043.1586Code snippet:#include <wuapi.h>#include <comdef.h>#include <atlbase.h>int _tmaini
