I would guess that the message's body (and maybe even the other strings)
should be escaped or quoted (by using ~w instead of ~s), probably the
parser for the resulting string can't handle the spaces and the '>'.

You should in any case sanitize the input, otherwise you will have problems
with code injection, imagine a message saying
"Hello&status=closed&time_create=..." (or worse).

best regards,
Vlad
