How do i use the sh_download.lua lib properly?

[Awerta Dreams]

I was interested in using sh_download.lua lib in my gmod project, but for some case i get this:

[ERROR] gamemodes/debugin/gamemode/lib/sh_download.lua:344: No callback for download on client
  1. error - [C]:-1
   2. func - gamemodes/debugin/gamemode/lib/sh_download.lua:344
    3. unknown - lua/includes/extensions/net.lua:38

How do i resolve this?

Nevermind, i actually didnt add callback on client.
