2019-05-20 00:44:34 -0500 marked best answer JointTrajectoryController ( no p gain specified)

hello all, am trying to move multiple joints of my delta robot using JointTrajectoryController ( I am using ROS kinetic) . but i am getting the following error:

No p gain specified for pid. Namespace: /gazebo_ros_control/pid_gains/Motor1_UpperArm1
No p gain specified for pid. Namespace: /gazebo_ros_control/pid_gains/Motor2_UpperArm2
No p gain specified for pid. Namespace: /gazebo_ros_control/pid_gains/Motor3_UpperArm3

The following is my .yaml file in the control package

delta_robot:
  # Publish all joint states -----------------------------------
  joint_state_controller:
    type: joint_state_controller/JointStateController
    publish_rate: 50  


  # Joint Trajectory Controller -------------------------------
  delta_position_trajectory_controller:
     type: position_controllers/JointTrajectoryController
     # CR: Here is my point, can the urdf/transmission specification be used for joint names?
     joints:
        - Motor1_UpperArm1
        - Motor2_UpperArm2
        - Motor3_UpperArm3
      gains:
       Motor1_UpperArm1:
     p: 10
         i: 1 
         d: 10
       Motor2_UpperArm2:
    p: 10
        i: 1 
        d: 10
       Motor3_UpperArm3:
    p: 10
        i: 1 
        d: 10

any idea how to fix this issue? Anyone can attach an exemple of the yaml file to do so?
