The body of message is the StdOut of the Task. That appears sometimes. It seems when use the {TASK(Active,StdOut)} we don't get anything but when you use something like {TASK(21a0d828-643f-4ae4-8eb7-857e886b4014,StdOut)} then we get the results. As far as the subjects, it does seem pretty consistent that we don't have one.
