createEncryptedAppTicket fails

[LunarN0v4]

I get the following when making an app ticket (user.createEncryptedAppTicket(appid, clientcallback)):

Error: Fail

Does the app in question actually use encrypted app tickets?

As far as I can tell, the app in question calls "GetAuthSessionTicket" from the Steam API.

https://partner.steamgames.com/doc/api/isteamuser#GetAuthSessionTicket

Here's the exact line where it calls this:

user.GetAuthSessionTicket(array, 1024, out ticket);

I have now realised what I've done wrong, it's an AuthSessionTicket, not an EncryptedAppTicket.

My bad.
