Error: processing vignette 'cartograflow_general.Rmd' failed with diagnostics:

I tried to install in R console pandoc as below

pandoc is not an R package, but an external tool. You can download and install it from Releases · jgm/pandoc · GitHub

Thanks I will try it.
So question : why is it possible to install it directly in R?

The pandoc R package is a development tool that would be most helpful to package developers. The average user probably wouldn't need it - you can read more about the package here: Manage and Run Universal Converter Pandoc from R • pandoc.

As @Gabor suggests, you should download the external tool from the link he provided.

Right, you need the external tool for rmarkdown. The pandoc R package helps you install pandoc (the external tool), if you want to use it, call pandoc::pandoc_install().
