Hi, I am using an **Intel RealSense camera** with the `realsense2_camera` ROS2 driver. When running my object detection node in stretch deep perception , I get the following error in the logs:

```auto
[realsense2_camera_node-4] [ERROR] [xxxxx]: Given value, 63 is invalid. Set ROS param back to 100

```

After this, the camera **stops the depth and RGB sensors**. So the Rviz opens but no Image is detected .

I suspect a parameter (possibly frame rate, exposure, or gain) is being **incorrectly set to 63** , but I am not sure which one.

### **What I’ve Tried:**

1. Listing active parameters using:

```auto
ros2 param list /realsense2_camera_node

```

In this it was saying node not found . Can someone help me with this problem .

Hi @Mayank_Anand , could you post the full log of the error you are facing ?  
The error message you mention realted to parameter `Given value, 63 ...` can be ignored and it shouldn’t be causing any issues.  
If you are running the realsense node from Stretch ROS2, for example:

```auto
ros2 launch stretch_core d435i_high_resolution.launch.py

```

The namespace of the node would be `/camera` and you can inspect if the camera data is being streamed by echoing any camera image topic or check the params using the following commands.

```auto
ros2 topic echo /camera/color/image_raw
ros2 param list /camera

```
