    When I try to launch the fourth part of the pick and place tutorial while following all the steps. I do not have any errors while running the part_4.launch script as well as when I play the Unity scene. However, when I press the button to activate the PublishJoints() function, unity shows the following error.

    Exception: No registered publisher on topic sim_real_pnp for type niryo_moveit/MoverService!

    When I search for the error in the RealSimPickAndPlace.cs, I reach the PublishJoints() functiun and the following line : m_Ros.Publish(rosJointPublishTopicName, request);

    I do not have a niryo robot I just want to know how the part 4 of the tutorial is working.
    The tutorial worked fine till this point. Is this error present because I do not have a niryo robot connected to my computer ? Or is it due to a missing message file ?

    Did you solve this issue? I am getting the same error. I also want to test if it works, but don't have the real robot at the moment.
