access violation reading position 0x0000000000000000

Hello,

I am a beginner with point cloud library and wanted to start by running some tutorials. When I tried the narf_keypoint_extraction following the steps from https://pcl.readthedocs.io/projects/tutorials/en/latest/narf_keypoint_extraction.html,I ran into an issue. The build with cmake was successful but a runtime error occured at line 161.

Error: Exception thrown at 0x00007FFF817356FD (vtkRenderingContext2D-9.0d.dll) in narf_keypoint_extraction.exe: 0xC0000005: access violation reading position 0x0000000000000000.

I read that this is due to dereferencing a null pointer but I don't understand why?

Shouldn't the tutorial work basically without any user input, as an example point cloud is generated, if no point cloud is passed by the user? Or am I forgetting something?

Any help is appreciated. Thank you!

Start with doc/tutorials/content/sources/narf_keypoint_extraction/narf_keypoint_extraction.cpp at line 161 and reproduce the runtime failure using the steps in the NARF keypoint extraction tutorial. Trace the access violation reported from vtkRenderingContext2D-9.0d.dll and verify that the tutorial completes without a null-pointer access violation.
