Hi,

This is the same error message as here, as it seems:

https://github.com/jgm/pandoc/issues/5943

Normally, since this commit, it should compile just fine with pandoc-types 1.2.0.

Are you sure you are compiling the latest version?

It seems that you are compiling v. 1.4.0.0, but you need at least v. 1.5.0.0 according to the changelog to compile with Pandoc 2.8 / pandoc-types 1.20.

This bug could be related as well: how are you getting the source code?

v 1.5.0.0 worked. Thanks @aubertc. I'm closing this issue.
