Uploading Problems with my Mod

[Argaros]

Hello guys

I just finished my first Mod for this game and it worked all fine. This mod only adds some music.
But I have problems to upload it into the Steam Workshop.
This is the error log:

Workshop: OnItemSubmitted failure. Result: Fail
UnityEngine.StackTraceUtility:ExtractStackTrace ()
Verse.Log:Error (string)
Verse.Steam.Workshop:OnItemSubmitted (Steamworks.SubmitItemUpdateResult_t,bool)
Steamworks.CallResult`1<Steamworks.SubmitItemUpdateResult_t>:OnRunCallResult (intptr,intptr,bool,ulong)
Steamworks.SteamAPI:RunCallbacks ()
Verse.Steam.SteamManager:Update ()
(wrapper dynamic-method) Verse.Root:Verse.Root.Update_Patch1 (Verse.Root)
Verse.Root_Entry:Update ()

I just dont know what Im doing wrong :/

I found out why it didnt work. If u have the game only through family sharing u cant upload objects into the workshop.
