`ros2 node list`, `ros2 service list` and `ros2 param list` randomly display information on Windows

[bananasmoothii]

Bug report

Required Info:

• Operating System:
  • Windows 11
• Installation type:
  • binary, installed from aka.ms/ros (I could not get the normal version working) with:

choco source add -n=ros-win -s="https://aka.ms/ros/public" --priority=1
choco upgrade ros-humble-desktop -y --execution-timeout=0 --pre

And my Microsoft.Powershell_profile.ps1 contains at the end:

$ROS_DOMAIN_ID=0
C:\opt\ros\humble\x64\setup.ps1

• Version or commit hash:
  • Humble Hawksbill
• DDS implementation:
  • Didn't touch that, I think the default is Fast DDS ?
• Client library (if applicable):
  • ?
• Python version in path (before ros2's setup):
  • 3.12.1

Steps to reproduce issue

Run

ros2 run turtlesim turtlesim_node

then

ros2 node list

a bunch of times, and

ros2 service list

a bunch of times.

Expected behavior

Command always containing the list of nodes / services

Actual behavior

The /turtlesim node was found 10 out of 16 times in my test

The services where found 8 out of 16 times in my test

Edit: I get the same bug with ros2 param list

When trying to get more information about a node or service that doesn't exist, for example ros2 service type /clear, the command just exits with exit code 1.

Additional information

When using rqt 'Plugins' > 'Introspection' > 'Node graph', nodes always display, and when using the 'Service Caller', services always show up.

A similar issue is #582 but this one seems to be fixed
