I would highly recommend to just fuel it directly from HWS Connect. After checking the chat logs, it looks like you just wrote “gold” as the resource name, but I think the OAM needs some specific names like you can see on this page (this page shows them for upgrading, though, but I expect it to be the same for fueling).
So said in another way, either use HWS Connect which is the easiest, or am:fuel:GO:3
