Unable to move the arm through Moveit...Error:Maybe failed to update robot state, time diff: 0,822s

Hi, I am trying to control gazebo simulated arm mounted on mobile base through moveit. When I try to execute the trajectories after setting starting and goal positions, I am getting "Maybe failed to update robot state, time diff: 0,822s"in my terminal. **When I remove robot_state_publisher from my launch file trajectories are being executed.** But i need tf tree to visualize octomap. my launch files: my moveit launch file: [/kate_jaco/joint_states] PS: I strongly feel, there is something wrong with the robot state publisher and tf_static topic published by it.
