I'm a novice, but this error happened to me when I did something like the following:

// the following will *error*
var element = $("#elementId");
$.post("/foo/bar/", { xxx : element });

Anytime you feed $.post something other than a string, JS errors. i.e., peId, pecatId, etc. must all be strings, not jQuery objects.
