Could not find the planner configuration 'None' on the param server

edit

Hello, I am trying to launch my launch file but I am met with a few error messages. The objective of this launch file is to use RVIZ to display my robot. I was able to bring up the RVIZ GUI but nothing else was showing up. The map display also mentions that there was no map specified. Please help, thank you.

The launch file contents:

<launch>
  <!-- The planning and execution components of MoveIt! configured to run -->
  <!-- using the ROS-Industrial interface. -->

  <!-- Non-standard joint names:
       - Create a file [robot_moveit_config]/config/joint_names.yaml
           controller_joint_names: [joint_1, joint_2, ... joint_N]
       - Update with joint names for your robot (in order expected by rbt controller)
       - and uncomment the following line: -->
  <rosparam command="load" file="$(find myworkcell_moveit_config)/config/joint_names.yaml"/>

  <!-- the "sim" argument controls whether we connect to a Simulated or Real robot -->
  <!--  - if sim=false, a robot_ip argument is required -->
  <arg name="sim" default="true" />
  <arg name="robot_ip" unless="$(arg sim)" />

  <!-- load the robot_description parameter before launching ROS-I nodes -->
  <include file="$(find myworkcell_moveit_config)/launch/planning_context.launch" >
   <arg name="load_robot_description" value="true" />
  </include>

  <!-- run the robot simulator and action interface nodes -->
  <group if="$(arg sim)">
    <include file="$(find industrial_robot_simulator)/launch/robot_interface_simulator.launch" />

    <!-- publish the robot state (tf transforms) -->
    <node name="robot_state_publisher" pkg="robot_state_publisher" type="robot_state_publisher" />
  </group>

  <!-- run the "real robot" interface nodes -->
  <!--   - this typically includes: robot_state, motion_interface, and joint_trajectory_action nodes -->
  <!--   - replace these calls with appropriate robot-specific calls or launch files -->

      <arg name="max_payload" value="5.0"/>
    </include>
  </group>

  <include file="$(find myworkcell_moveit_config)/launch/move_group.launch">

  </include>

  <include file="$(find myworkcell_moveit_config)/launch/moveit_rviz.launch">
    <!-- <arg name="config" value="true"/> -->
  </include>

</launch>

After running $ roslaunch myworkcell_moveit_config demo.launch

There is an error message which shows:
