Description

Tried following the "Your First C++ MoveIt Project" but on running my new node it outputs the following :
[ERROR] [1677885102.756933441] [moveit2_unity_node]: Could not find parameter robot_description_semantic and did not receive robot_description_semantic via std_msgs::msg::String subscription within 10.000000 seconds. Parsing robot urdf xml string. Error: Could not parse the SRDF XML File. Error=XML_ERROR_EMPTY_DOCUMENT ErrorID=15 (0xf) Line number=0 at line 694 in /tmp/binarydeb/ros-foxy-srdfdom-2.0.2/src/model.cpp [ERROR] [1677885102.760612081] [moveit_rdf_loader.rdf_loader]: Unable to parse SRDF [FATAL] [1677885102.761152701] [move_group_interface]: Unable to construct robot model. Please make sure all needed information is on the parameter server. terminate called after throwing an instance of 'std::runtime_error' what(): Unable to construct robot model. Please make sure all needed information is on the parameter server.
after some inspection I can see that the node doesn't have the required rosparamters , however, the documentation doesn't state that I should create a launch file or pass in the parameters anywhere else.

this is the exact error mentioned here #528 However the solution for the mentioned issue was to follow the "Humble installation guide" and I followed it , with changing Humble branch with foxy branch in this step git clone https://github.com/ros-planning/moveit2_tutorials -b humble --depth 1 -> git clone https://github.com/ros-planning/moveit2_tutorials -b foxy --depth 1
I'm not aware of any other changes that I should do

Your environment

• ROS Distro: Foxy
• OS Version: Ubuntu 20

Steps to reproduce

Follow the exact steps of the https://moveit.picknik.ai/humble/doc/tutorials/your_first_project/your_first_project.html
tille the "Build and run" Section

Expected behaviour

Node runs and robot in Rviz start excuting the planned motion

for anyone still facing this in the future , add these paramters into the demo.launch.py in the moveit2_tutorials
"publish_robot_description": True, "publish_robot_description_semantic": True, this was mentioned in another issue but I missed it.
