MoveIt found solution, but is unable to solve the planning problem

edit

Hi,

I am facing a very strange problem. I am sending a goal in joint space with a real UR5 like

def go_with_joint_values(mgc, jvs):
    mgc.set_joint_value_target(jvs)
    success = mgc.go()
   mgc.stop()
   mgc.clear_pose_targets()
   rospy.sleep(rospy.Duration.from_sec(1))
   return success

But I get this output from MoveIt:

 [ INFO] [1675737816.007575299]: Combined planning and execution request received for MoveGroup action. Forwarding to planning and execution pipeline.

I really do not understand the problem (a couple of weeks ago it was all ok...). With rviz I am able to move the robot to a pose that is very close to the target one. Also using setting a goal in cartesian space works. I am using a dual arm system and the other robot has no problems.

Any suggestion on how to debug this error?

Thank you in advance!
