HI all! I'm trying create a moveit package for my own robot following the tutorial [Create_a_MoveIt_Pkg_for_an_Industrial_Robot](http://wiki.ros.org/Industrial/Tutorials/Create_a_MoveIt_Pkg_for_an_Industrial_Robot). When I finished the second part **Update Configuration Files** I tested the configuation.However, there was something wrong. When I start the planning _and_execution.launch, there was something output like this:
[mongo_wrapper_ros_shantengfei_PC_9122_1384786663048058499-7] process has died [pid 9194, exit code 1, cmd /opt/ros/indigo/lib/warehouse_ros/mongo_wrapper_ros.py __name:=mongo_wrapper_ros_shantengfei_PC_9122_1384786663048058499 __log:=/home/shantengfei/.ros/log/e378d02c-b477-11e7-9896-7085c22fcebd/mongo_wrapper_ros_shantengfei_PC_9122_1384786663048058499-7.log].
log file: /home/shantengfei/.ros/log/e378d02c-b477-11e7-9896-7085c22fcebd/mongo_wrapper_ros_shantengfei_PC_9122_1384786663048058499-7*.log
Moreover, when I moved the end of my robot to a new goal and clicked the button **plan and execute** therwere also something incorrect like this:
[ERROR] [1508380543.575187832]: Found empty JointState message
[ERROR] [1508380543.575242498]: Found empty JointState message
[ERROR] [1508380543.575402437]: Found empty JointState message
[ERROR] [1508380543.575685878]: Found empty JointState message
When I tried first **plan** and then **execute** the error `[ERROR] [1508380543.575685878]: Found empty JointState message` didn't appear. So could someone told me how to cope with these errors?
