Describe what you want to implement and what the issue & the steps to reproduce it are:

I want to specify user id via config_file, which in this case is default.yaml, I have tried to configure it using following ros2 command "startup_user_set:=Default" but i face the following error.

pylon_ros2_camera_wrapper-1] 1718269086.782112861 [basler.pylon.ros2.pylon_ros2_gige_ace2_camera] [ERROR] Error applying camera specific startup setting for GigE cameras: Parameter not found in CFloatParameter::GetMax.

Hello @tui-abdul Thank you for reporting this issue. I am sorry I don't manage to reproduce it. Can you tell me a bit more about how you set the startup_user_set. Do you do it through the default.yaml file, the launch file itself og the launch command line arguments? Beware that some parameters implemented by the driver, like for instance the parameter startup_user_set, can be set through 1. the pylon_ros2_camera_wrapper/config/default.yaml user parameter file, 2. the pylon_ros2_camera.launch.py driver launch file, and 3. the command line arguments of the launch command to start the driver. A parameter value set as an argument of the launch command to start the driver will overwrite the value set in the driver launch file itself, that will overwrite the value set in the user parameter file.
