After much searching and testing, I found out that the problem was not with tinytex or pdflatex, but rather my call to rmarkdown::render() That led me to this answer on GitHub https://github.com/rstudio/shiny/issues/1831. Apparently, when rmarkdown::render() is called within downloadHandler(), you should NOT specify the output_file argument in render() Instead you need to rename the file AFTER rendering.

Here is the correct code (simply replace the call to downloadHandler() in the script from my original question.

Check your header. Some posts (i.e. here) report that the correct way to specify engine is

• \usepackage[utf8]{inputenc} not necessary if your tex distribution was updated in the past couple of years

• \usepackage{parskip} not necessary, beamer does not indent paragraphs

• \usepackage{graphicx} not necessary, beamer loads this already

• \usepackage{float} \floatplacement{figure}{H} not necessary, beamer does not have a floating mechanism

• \usepackage{xcolor} not necessary, beamer loads this already

• \usepackage{enumerate} not necessary, beamer has it's own mechanism

• \usepackage{geometry}, \usepackage{amsmath}, \usepackage{amssymb} not necessary, beamer loads this already

• \usepackage{hyperref} not necessary, beamer loads this already

• \usepackage{titling} don't use this with beamer

• \usepackage[inline]{enumitem} don't use with beamer

• \hypersetup{...} don't do this. Beamer carefully sets up all the colours for the footline etc and this destroys the whole layout

• \geometry{...} don't do this. Beamer carefully sets up the pagelayout and this destroys it

• you must use the \begin{frame}[fragile] option if you have such fragile content

Update: This is possible in pandoc 2.11. For details, see the MANUAL, but for example:

It seems like you have at least three options (and you do not need docker):

The Ubuntu GitHub Runner already has linuxbrew installed (last bullet in the linked document).

You might encounter issues here, since this environment will not be completely compatible with your mac.

Find the respective apt packages for the ones you currently install with brew, and install them normally with a run directive.

This is probably the most suitable for you. If you want the CI environment to more closely resemble your personal environment, run on a mac runner instead of an ubuntu runner. These are the supported environments - you will probably want runs-on: macos-latest. The software installed on the GitHub mac runner is listed here.

Unfortunately matplotlib 3.1.1 broke seaborn heatmaps; and in general inverted axes with fixed ticks.
This is fixed in the current development version; you may hence

• revert to matplotlib 3.1.0
• use matplotlib 3.1.2 or higher
• set the heatmap limits manually (ax.set_ylim(bottom, top) # set the ylim to bottom, top)

Seeing this gave me an idea : I inserted the line

You could use this code, which we also use with pandoc/lua-filter to always use the latest pandoc version:
