my moveit demo.launch file gives such error, but i do not know which cause it. do you know something about such error?

i use such plugin in urdf as follows

..................... L_thumb_proximal_pitch_joint L_thumb_intermediate_joint 1.6 0.0 R_thumb_proximal_pitch_joint R_thumb_intermediate_joint 1.6 0.0 L_thumb_proximal_pitch_joint L_thumb_distal_joint 2.40 0.0 R_thumb_proximal_pitch_joint R_thumb_distal_joint 2.40 0.0 L_index_proximal_joint L_index_intermediate_joint 1.0 0.0 R_index_proximal_joint R_index_intermediate_joint 1.0 0.0 ^^^^^^^^^^^^^^^^^^^^ what's more, i have set the mimic joints such as L_thumb_intermediate_joint

as passive joints in moveit.just because:https://answers.ros.org/question/220354/error-group-has-mimic-joint-will-not-initialize-dynamics-solver/
but i have not seen some helpful solutions! i hope some help! Thanks very much!
