PlotJuggler in ROS2 Launch file

[gurbain]

Problem description

I am struggling to start plotjuggler in a ROS2 launch file. It seems that starting a Node in a launch file automatically passes the --ros-args argument and plotjuggler does not handle it. Is there a way to circumvent this, while using the Node class of ROS2 launch actions (and not ExecuteProcess)? Thank you!

Steps to reproduce

• Platform: ROS2 Foxy on Ubuntu 20.04
• Sample launch file:

from launch import LaunchDescription
from launch_ros.actions import Node

def generate_launch_description():
    node_plot = Node(
        package='plotjuggler',
        executable='plotjuggler')
    return LaunchDescription([node_plot])

• Behavior:

$ ros2 launch plot plot.launch.py
[INFO] [launch]: Default logging verbosity is set to INFO
[INFO] [plotjuggler-1]: process started with pid [21577]
[plotjuggler-1] QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
[plotjuggler-1] Unknown option 'ros-args'.
[ERROR] [plotjuggler-1]: process has died [pid 21577, exit code 1, cmd '/opt/ros/foxy/lib/plotjuggler/plotjuggler --ros-args'].

Hi @facontidavide I know this has been closed, but I am facing the same issue, if there is no solution, what would you advise to do if I would like to launch plotjuggler with a launch file in ROS 2?

Will think about this

Might the removeROSArgs() (ROS1) or remove_ros_arguments() (ROS2) functions be of help? As the name says, they remove ROS arguments, allowing the code after it to work without the ROS arguments being in the way.

I did not know about that. Sound as the right solution
