unrecognized 'param' tag in <include> tag while launching moveit gazebo demo

edit

Hello, When using "roslaunch dobot_moveit_config demo_gazebo.launch", I get this error message

nabil@nabil-VirtualBox:~/dobot_ws$ roslaunch dobot_moveit_config demo_gazebo.launch 
... logging to /home/nabil/.ros/log/ed111fe4-547e-11ec-bdaa-0800279cc1e2/roslaunch-nabil-VirtualBox-3484.log

RLException: unused args [execution_type] for include of [/home/nabil/dobot_ws/src/dobot_moveit_config/launch/dobot_v1_moveit_controller_manager.launch.xml]
The traceback for the exception was written to the log file

and this is the dobot_v1_moveit_config_controller_manager.launch.xml file:

<launch>

  <!-- loads moveit_controller_manager on the parameter server which is taken as argument
    if no argument is passed, moveit_simple_controller_manager will be set -->
  <arg name="moveit_controller_manager" default="moveit_simple_controller_manager/MoveItSimpleControllerManager" />
  <param name="moveit_controller_manager" value="$(arg moveit_controller_manager)"/>

  <!-- loads ros_controllers to the param server -->
  <rosparam file="$(find dobot_moveit_config)/config/ros_controllers.yaml"/>
</launch>

What may be the possible issue here?
