something wrong when start the moveit package of my own robot

HI all! I'm trying create a moveit package for my own robot following the tutorial CreateaMoveItPkgforanIndustrial_Robot. When I finished the second part Update Configuration Files I tested the configuation.However, there was something wrong. When I start the planning andexecution.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?

I don't know about the Mongo DB error, but the "Found empty JointState message" errors are a known issue. See ros-planning/moveit#579. It should also have been fixed, see ros-planning/moveit#589.

But that fix is only available in a source build, as it hasn't been included in a binary release yet.

Thanks gvdhoorn. But I cannot find the path moveit_core/robot_state/src/conversions.cpp in my PC.So How to change it?

Don't change individual files, it will most likely not work.

If you can't wait for the empty JointState fix, do a source install of MoveIt. But it's most likely not really important.

Many people said this error doesn't have side effect,Right? In this case I will wait for the fixed.
