ros_gz_bridge parsing parameter problem

[xxh3289147418]

Issue in ROS 2 Jazzy's display.launch.py
At line 40:

python
Copy Code
ros_gz_bridge = RosGzBridge(
bridge_name='ros_gz_bridge',
config_file=bridge_config_path,
container_name='ros_gz_container',
create_own_container='False',
use_composition='True',
)
Runtime Error
The __extra_bridge_params parameter fails to parse correctly in ros_gz_bridge.py:

python
Copy Code
parsed_bridge_params.update(self.__extra_bridge_params[0])
Error trace:

text
Copy Code
File "/opt/ros/jazzy/lib/python3.12/site-packages/ros_gz_bridge/actions/ros_gz_bridge.py", line 246, in execute
parsed_bridge_params.update(self.__extra_bridge_params[0])
~~~~~~~~~~~~~~~~~~~~~~~~~~
IndexError: string index out of range
Temporary Workaround
Manually inject parameters:

python
Copy Code
ros_gz_bridge = RosGzBridge(
bridge_name='ros_gz_bridge',
config_file=bridge_config_path,
container_name='ros_gz_container',
create_own_container='False',
use_composition='True',
extra_bridge_params=[{'use_sim_time': LaunchConfiguration('use_sim_time')}]
)
Recommended Fix
Add parameter validation in RosGzBridge class to handle empty/undefined __extra_bridge_params cases.
