It only recognizes the messages of ROS2

[serkanMzlm]

Problem description

I created my own message type in ROS2 and executed . install/setup.bash in the terminal. I can print the published message to the screen using ros2 topic echo. However, when I tried to include it in the plotjuggler application in the same terminal, the topic part gave me a warning

Describe the problem and the expected behavior. Use screenshots or a video, if applicable.

Answer these questions (or I will ignore your issue)

1. Describe your platform / Operative System and the version of PlotJuggler you are using.

• OS: Ubuntu 22.04 LTS (Jammy Jellyfish)
• PlotJuggler Version: 3.9.1
• ROS2: Humble

2. Compile and try the latest version in the main branch and check if the problem persists.

• Sure, the error persists

3. Check if the problem can be reproduced using the dummy data created by the command line argument "-t" or one of the files in the folder "datasamples".

• The error is due to the topic's data type not being directly from ROS2's original data types.

4. If it can't be reproduced with the dummy data, please share the CSV file or the rosbag that can be used to reproduce the problem.

I installed sudo apt install ros-humble-plotjuggler-ros, and now when I run ros2 run plotjuggler plotjuggler it works. However, when I run the regular plotjuggler, it still gives the same warning.

That one threw me for a loop as well... thanks!
