Problem launching Intel Realsense D435 camera

edit

I’m trying to integrate an Intel RealSense D435 camera to try out some SLAM algorithms.I encountered an error mentioned here . As suggested i tried to apply the fix provided here. I did this however in the original realsense_node_factory.h file while retaining a copy of the original file.When this previous solution didn’t work for me i deleted the original and tried to use the copy of the realsense_node_factory.h file that i had saved earlier.When i tried to run the demo_pointcloud.launch i get errors as shown below.
