@staff In ROS Basics in C++,Unit 5, I am trying to run call a service programmatically according to tutorial.
When i include the launch file for the server
start_service.launch in the launch file for the service client, it gives error, but when i run them in 2 different launch files, it works as intended.
When using a single launch file:
<launch> <include file="$(find trajectory_by_name)/launch/start_service.launch"/> <node pkg ="service_client_pkg" type="service_client_pkg_node" name="service_client_node" output="screen"> </node> </launch>

Can i know why this is happening?
Feedback to @staff
under Exercise 5.1, please include which service we should launch, that is, please include the line below:
roslaunch trajectory_by_name start_service.launch
