Node-red-contrib-static-markdown is reporting TypeError: Cannot read property 'attrJoin' of undefined

General

node-red-contrib-static-markdown seems to provide the exact functionality I need but I am facing a little issue:

I have cloned the github repository:

so that I can test that the markdown in the example folder docs/test-md-library is properly rendered.

This seems to be the case for the index.md but not for the test.md in same folder.

So this is what I get when navigating to test.md:

Note that it seems to be working fine for index.md. So when navigating to http://127.0.0.1:1880/md or http://127.0.0.1:1880/md/index.md : I am seeing the following page:

I think it is a markdown library compatibiity issue that is described in

as I am getting the same error for my file test2.md with following content:

This is a paragraph of text with a *highlighted*{.hi} word in it.

It gives error

I guess/hope this also means that the bulk of the markdown will work and that there is only an issue when using special markdown.

I have also reported this issue in the github repository

... but sofar it is not blocking anything for me. The excellent node provides exactly what I need !
