Optional command idents not working

FlightAware ADS-B Flight Tracking
1

I am trying to execute below command to get the position of a Flight, but it never executes.
However when i removed the idents. it works.

Whats wrong with this command?
live username Sensitech password 352352e3452345 compression deflate events position idents EJA784

Works with below command though:
live username Sensitech password 352352e3452345 compression deflate events position
