ROS Melodic : pcl running error

[Taysssir]

Hi,
I'm using the ROS Melodic with the PCL-based detector. When I run I got this error :

Failed to find match for field 'rgba'.

Could you help me?

Thanx

I think its 'rgbd'

@RohanDwivedi, Thanks for your reply.
But as I mentioned before, I'm trying to use PCL Detector. So I set the right Point Cloud 2 Topic via Remap then the detector return this error: Failed to find match for field 'rgba'
