I'm having issues with ROS /clock not being published. I am running a simulation in Gazebo on Ubuntu 20.04. My code is getting stuck on a simple action client wait for server function.
To check if it was being sent anything, I rostopic echoed the client's topic and got this error: WARNING: no messages received and simulated time is active. Is /clock being published?
. So I also echoed /clock and got the same error. I do not believe my simulation was paused, which is what I've seen as an explanation online. Any idea how to get the simulation clock to publish correctly?
