Error when using moveit alongside gazebo

edit

With the (lack of) information given, I can't say for sure. But, from the warning that you posted there's a timeout issue.Your model may not be publishing the joint states on the correct topic. From @gvdhoorn's comment on this answer, you can try making

sure that joint_state_publisher gathers the JointStates published on /move_group/fake_controller_joint_states and republishes them on /joint_states.

with

<node name="joint_state_publisher" pkg="joint_state_publisher" type="joint_state_publisher">
    <param name="/use_gui" value="false"/>
    <rosparam param="/source_list">[/move_group/fake_controller_joint_states]</rosparam>
</node>

You can always use a Google search of ROS Answers and the error which will give many results.
