Any idea how could I make it work again?

Can you provide a link to a repository from which we can reproduce your issue? We can't do it from a description. We need "the whole file rather than the snippet you believe is causing the issue", like you checked on the box.

Thank you for the quick reply.

Here is the repo:

You can replicate by render the template.qmd file

This is fixed now - it should be available in our next release.

Should this get back ported to v1.3? I'm thinking anything that broke existing user or 3rd party filters should be back ported unless its extra hairy. @dragonstyle and @cscheid do you agree?

[cscheid]

It's a very simple fix. Agreed on backporting.

[dragonstyle]

Yes agree

This is now cherry-picked into our v1.3 hotfixes branch.
