I am trying to get a graph of what is running on my turtlebot but when I start rxgraph after the turtlebot_bringup.launch it stops and says there is an index out of range error. Here is the output from the terminal where I ran rxgraph:

Traceback (most recent call last):
  File "/opt/ros/diamondback/stacks/rx/rxgraph/src/rxgraph/", line 123, in run
    changed = g.update()
  File "/opt/ros/diamondback/stacks/ros_comm/tools/rosgraph/src/rosgraph/impl/", line 568, in update
        updated = self._node_refresh(next) or updated
  File "/opt/ros/diamondback/stacks/ros_comm/tools/rosgraph/src/rosgraph/impl/", line 452, in _node_refresh
    updated = self._node_refresh_businfo(node, api, bad_node)
  File "/opt/ros/diamondback/stacks/ros_comm/tools/rosgraph/src/rosgraph/impl/", line 407, in _node_refresh_businfo
    connection_id = info[0]
IndexError: list index out of range

As a final note, rxgraph runs fine with other applications but with the turtlebot_bringup.launch it produces the above.

Any ideas?

This is a known bug in rxgraph ticketed here:

you can use rosnode list to see the list of node running on your TurtleBot
