Connecting to multiple robots

[REGATTE]

Hi, I'm trying to run a simulation for fleet management with multiple robots on Isaac sim. I have setup 5 nova carter robots, and want to task them with missions. I followed the tutorials and was able to get the tutorial running. But when I put more robots, the mission dispatch shows robots task state changing to RUNNING, and then it FIALS.

How do I connect to multiple robots in simulation? When I send the /get API, I receive the robot initial pose, but can't seem to control them. I have setup node_namsepaces for all the robots, and when activating mission client, I give the param use_namespace:=True and namespace:=<robot_nodename>. How do I go about this?
