I added following github repo and github workflow that show this issue.

This makes me thing of this other issue:

• Compilation failed to PDF with Quarto 1.4.358 #6819

which was a problem with upstream Pandoc

• Document without citation doesn't get compiled jgm/pandoc#10185

It has been now fixed in Pandoc 3.5 and there should not be any more error like this when no bibliography file is provided.

Pandoc 3.5 will be integrated in Quarto in a later version that should fix this problem. When this is done, I'll check for what happens in your reported example.

Thanks again for the feedback
