Hello everyone ! I am trying to implement service type communication in ROS when i used terminal of operation to type the command and establish server-client communication, it works fine but when i use service caller in RQT to call the client, the following error appears:

ibrahim@ibrahim-Aspire-V5-591G:~/catkin_ws$ rqt
ServiceCaller.on_refresh_services_button_clicked(): could not get class of service /ros_tutorial_srv:
Unable to load type [ros_tutorials_service/SrvTutorial].
Have you typed 'make' in [ros_tutorials_service]?

Anyone have experience regarding this matter. Please reply. Thanks

Go to your project root dir, compile the project and do:

source devel/setup.bash

That should do it.
