It says "butler: error: unexpected Chaserchim/UnderworldExpedition"
And yes I have a game page set up.
Oh I actually missed it. The path needs to be encased with double quotes since it contains a space. So it should be:
butler push "c:\Users\chase\Documents\Unreal Projects\PackagedP1" chaserchim/UnderworldExpedition:windows
Let me know if that works.
Now it says "Invalid Game"
Edit: I got it, thanks for the help.
