Invalid API Version

[Rutrum]

I have a test file that looks like this, note that it doesn't use any include syntax.

When I compile this using the filter like so

pandoc -t latex -f markdown --filter pandoc-include -o test.pdf test.md

I get the following error

I get similar errors when using the include syntax. I installed this using pip, and pip show pandoc-include reveals that I am using version 1.2.

Oh my, I never considered upgrading pandoc from version 2.5 to 2.19. This fixed the issue, sorry about this.
