I am trying to publish a message to a ROS topic. The topic is one of the ROS topics available in the DJI drone ROS OSDK. Please see image 1 below. I'd like to publish roll angle, pitch angle, yaw rate and z position commands to the corresponding ROS topic. I'm using a Bus create at the input of the Publish block. However, I get the error shown in the next images. Could you please advise how I may resolve this?
