[Freeswitch-users] myevents json and xml arguments throwing errors

Hi everyone, I've been trying to use the myevents command to subscribe to the events for an api call, but I've been having some trouble. When I call: myevents <uuid> from my app (or even from a telnet client), I receive back all the event data just fine and the socket closes once the call has completed. However, if I pass a format argument, i.e: myevents json <uuid> I receive a response of: ERR invalid uuid My uuids are definitely valid. The command breaks for all format arguments too (xml, json and plain). Has anyone encountered this problem before? Documentation for myevents is a little light, and web searches so far have been fruitless. Thanks, Adam
