Error: pandoc document conversion failed with error 83

Hi, I'm not sure if this has to do with the scholarly-metadata.lua or author-info-blocks.lua files directly, but I recently updated my R and R studio versions and a file that was working fine is now giving an error. Below is a simple example that gives the error

Error running filter author-info-blocks.lua:
author-info-blocks.lua:100: bad argument #2 to '__concat' (table expected, got nil)
stack traceback:

Below is the code I ran to get this error:

I am using rmarkdown to create documents, which uses pandoc. When I want to create a document I just hit the `knit` button in R studio. So when I opened up a file containing the code above and hit the knit button, I got the error above.

Here is the result of calling `print(sessionInfo(), locale = FALSE)`

R version 4.2.0 (2022-04-22 ucrt) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows 10 x64 (build 16299)

And the result of `rmarkdown::pandoc_version()`

‘2.17.1.1’



Please let me know if there is any other information that would be useful in trying to fix this issue.
Thanks
