What does "JSON KO response: "heroId" JSON parameter is not set" mean?
This was the answer to "http://heroesweb.ubi.com/ajax/getFrame.php?json={%22heroId%22:null,%22regionId%2 2:%22285%22,%22elementType%22:%22ScoutingFrame%22, %22elementId%22:%22null_285%22}", when I wanted to scout a foreign region.

Is "heroId" not set because my hero is busy?

PS: Non-url-encoded request parameter: json {"heroId":null,"regionId":"285","elementType":"Sco utingFrame","elementId":"null_285"}

[PPS: d'uh. I read herold instead of hero ID. I think, a herold (or herald?) is some kind of messenger. Like someone you could use for scouting...]
