[DDS_RETCODE_BAD_PARAMETER] Bad parameter value In ROS2 foxy execution

[incheol67]

Hello,
I encountered an issue while using CycloneDDS communication.

When I run a regular Python script, everything works fine without any errors. However, when I run a ROS 2 node, I get the following error:

📌 [Error message: BAD PARAMETER]

I tried debugging this bad parameter issue, and I found that the values being passed when running the regular Python script and the ROS 2 node are exactly the same.

🚨 So why does it fail only in ROS 2?
What could be causing this issue specifically when running the ROS 2 node?
