Interpolation node dying while using Ouster OS0-32U Lidar instead of Velo.

[kumar-abhina]

Greetings,
I have been following this repo for quite a while as a part of my project. I am using Ouster OS0-32U lidar which has a 32 laser scans (instead of 16 for velo puck). I have changed each and every subscribing and publishing topics as per my dataset. Below is my setup:

• Ouster OS0-32U lidar
• Intelrealsense 435D Stereo Camera.
  As per my data I ahv also followed the previous inssues here and here but they don't seem to solve our issues. After everything, the interpolation node is dying because of some unknown reason. I am kind of aware about the issue (not sure though) but I don't know how and where I can perform these changes.
  So the Velo lidar has 4 channels whereas the Ouster lidar has 9 channels as per the datasheet. Below is my output. This code works

Hi, the number of channels of the sensor does not interfere in the interpolation of the data, since only the interpolation is done in a range image using the X,Y,Z channels.
I would like to see the modifications you have made to the repository, could you create a fork of the repository so I can review it?
I think the error occurs when running through one of the for loops, but I don't know where in the code.
