noone can help if you don't provide the needed information.
Your gitCommitish _may_ be the same as in
https://github.com/openlilylib/snippets/blob/master/editorial-tools/git-commands/
or not. Noone can tell.
A minimal working example with the used version would have been nice as well.


So for now I _guess_ you took it from there.

The problem then: `bookOutputSuffix' expects a string, but you provide
a markup. Can't work.
Different possibilities to proceed:
- catch what you need from the markup-command and write something
outputting a string
- markup->string

Cheers,
