Rtabamap GUI Settings parameters error

[Rutika1212]

I followed the steps on this link https://github.com/introlab/rtabmap/wiki/Change-parameters after which I am getting this error. I wanted to create accurate 3D map. After which I will convert 3D map to 2D map for navigation purpose.

The map earlier I created was a bit distorted, therefore I decided to tune the prameters of the rtabmap and create a good 3D map. Following commands were used for 3D mapping. I am using Intelrealsense D435 camera and Jetson orin nano hardware.

ros2 launch realsense2_camera rs_launch.py depth_module.profile:=424x240x30 enable_depth:=true rgb_camera.profile:=424x240x30 pointcloud.enable:=true align_depth.enable:=true enable_sync:=true

ros2 launch rtabmap_launch rtabmap.launch.py rgb_topic:=/camera/color/image_raw depth_topic:=/camera/depth/image_rect_raw camera_info_topic:=/camera/color/camera_info approx_sync:=true frame_id:=camera_link map_frame_id:=map publish_tf:=true database_path:=~/rtabmap.db rgbd_sync:=true qos:=1 Vis/MaxDepth:=4.0 Grid/3D:=true Grid/RangeMax:=5.0 Mem/IncrementalMemory:=true Rtabmap/DetectionRate:=1.0

I was able to create a better map.

I accidently deleted the config.ini file from ~/.ros path also.

Below is the video of my earlier 3D map

Now I want my rtabmap parameters as the earlier how to do it. Also the Source and Rtabmap settings are grayed out. Earlier I was able to acces Advanced settings but now I am not able to. Please guide me.

If the UI cannot get parameters from the rosparam server, it means rtabmap node is down. you can look for potential errors on the terminal when you open Preferences dialog.
