Quarto 1.4 gives an error when rendering a dashboard format document

As the title says, I've not been able to render a dashboard format with the newly installed Quarto 1.4.
I also have the newest R version (3.4.4) and the newest RStudio version (2023.12.1 Build 402)

I just have this little code:


title: "Quarto Dashboard Test"
format: dashboard

plot(cars)

This is the error it gives upon rendering:

==> quarto preview Quarto Dashboard Test 001.qmd --to dashboard --no-watch-inputs --no-browse

ERROR: Validation of YAML front matter failed.
ERROR: In file Quarto Dashboard Test 001.qmd
(line 3, columns 9--17) Field "format" has value dashboard, which must instead be 'asciidoc'
2: title: "Quarto Dashboard Test"
3: format: dashboard
~~~~~~~~~
4: ---

ERROR: Render failed due to invalid YAML.

I hope that someone knows how to fix this. All help is appreciated :smiley:

I'm getting the same error.

RStudio Version 2023.12.1+402 (2023.12.1+402)

I believe the latest version of RStudio Desktop bundles Quarto 1.3, and dashboards require 1.4. I resolved the issue by downloading a daily build here: https://dailies.rstudio.com/
