Stamp not rendering

[jarrodscott]

Howdy!

I was able to install the extension successfully however no stamp renders in my final document, including when I use the minimal example. The page renders fine, no errors, just no stamp. Directory tree, minimal example, and session info below. any help would be most appreciated :)

I should add that, per the instruction here, document-information is not in the final HTML file

quick follow-up in case anyone else is having a similar issue. Turns out that having the quarto extension downloadthis is somehow causing a conflict with stamp. even if I am not using downloadthis, just that it is installed prevents stamp from rendering

So, the short gist is the problem is with downloadthis and how stamp is reading its metadata? Or?
