Ros1_bridge output

Screenshot from 2017-09-17 10-44-27

I am running the ros1_bridge tutorial in a Ubuntu 16.04 machine.As one can see in the lower left terminal , it is sometimes printing " Failed to load ‘request_type’ from a header for …".
Can anyone explain the cause for this ?

Yes this is a spurious warning that shouldn’t prevent you from running the bridge. Apparently this field is used only by roscpp but not rospy in ROS1. The bridge doesn’t need them to work so we removed the checking of these fields recently (see https://github.com/ros2/ros1_bridge/pull/91).
This patch has been released in beta 3 so updating your code to the latest version should make these warnings disappear.

Hope this helps
