I'm getting this same error when running the code provided in README.md

quarto use template quarto-journals/acm
quarto render article.qmd --to acm-pdf

This is on quarto v1.5.55.

Makes me think it could be helpful to add these officially-supported templates into the test suite.

Ah, this is strange: quarto use template quarto-journals/acm copies into the directory the contents of this repo ...except the _extensions subdirectory is empty. This can be fixed by also running quarto add quarto-journals/acm but something must be going awry in the detection of the extension within the template.

This extension needs a fair amount of updating; I hope to get this done by the end of August. Thanks for the patience, everyone.
