Pick and place issues in Moveit

edit

I learned the Pick and place tutorial in Moveit and ported it to our own virtual robot model. The tools I used in the experiment were: ROS1+Moveit+Rviz

After successful compilation, I executed the following error:

configuration parameters will be set when the planner is constructed.

**[ERROR] [1548253404.233262963]: Joint trajectory action failing on invalid joints

If anyone can give me a good suggestion, I will be very grateful!

Thank you.
