LanSweeper TicketAPI - SearchTickets doesn't work with "AgentID"

[AxelK]

Hello,

i am currently working on a Dashboard for our IT Department, so we can have a quick look at a big screen to view if there's unassigned tickets at a glance instead of always switching tabs.

I want to have a little stat of unassigned Tickets, but i sadly cannot seem to query unassigned tickets, as adding the "AgentID" Query seems to break searches.

This gives me 0 results (but success)(there are unassigned open tickets, i left some for test purposes):
https://server/api.aspx?key=1234&action=SearchTickets&state=open&AgentID=0

This gives me all tickets currently marked as "Open" correctly:
https://server/api.aspx?key=1234&action=SearchTickets&state=open

Does anyone have an idea, why this happens?
We are curently running v. 12.1.0.1

Oh yeah, quick Addition:
I have also tried searching (unopened tickets and generaly tickets) with for instance my AgentID, which yielded the same result as AgentID 0.
