Do you have “fast cast ground targeting” turned on in options? If so, it’s trying to fire the trebuchet at your mouse cursor, which is probably in an invalid position for the trebuchet.
If I recall correctly, there are two trebuchets. I managed to use one of them successfully each time I’ve been in the instance, but not the other.
