htmlwidgets::saveWidget Error: pandoc document conversion failed with error 97

I always use htmlwidgets::saveWidget to save my Plotly html plots in R. For some unknown reason, I started to get:

Could not find data file templates/file6efb40d38e3c.html                                        
Error: pandoc document conversion failed with error 97                                       
Execution halted   

I first thought I had some problems with the temp dir so I tried to add dir.create(tempdir()) but it wasn’t it. After some more digging I found this GitHub issue and answer from cpsievert, which solved the issue.

Instead of using file=outputdir/filename.html, what I usually use to export/save everything in R, I had to split it into file=filename.html and libdir=outputdir. The error dissapeared and I could happily save my beautiful Plotly html plots.
