Unable to plan motion using python file from demo 3.1

When I have a move_base node running and try to execute the python file for sending a goal to moveit.Rviz, I am getting the following error. Any help would be appreciated.

[ INFO] [1581124988.872156939, 698.221000000]: Planning request received for MoveGroup action. Forwarding to planning pipeline.

I also get a warning when I launch the move base launch file

[ WARN] [1581126376.034840604, 25.655000000]: Interactive marker ‘EE:goal_wrist_roll_link’ contains unnormalized quaternions. This warning will only be output once but may be true for others; enable DEBUG messages for ros.rviz.quaternions to see more details.

Hello @hrushikesh.kyathari,

The Warning message about the marker is not relevant in this case, so don’t worry about that. The problem here appears to be that the goal is not reachable for some reason. Are you using the goal values from the example? Could you try with different goal values?
