Bookdown fail to create PDF when reference inside table generated by knitr::kable

[raniere.silva]

Consider the following minimal working example:

---
title: Minimal Working Example
author:
- Raniere Gaia Costa da Silva
date: "2021-04-19"
site: "bookdown::bookdown_site"
documentclass: article
bibliography: reference.bib
link-citations: yes
---

```{r , echo=FALSE, message=FALSE}
library(tidyverse)
df <- read_csv("./data.csv")
df %>%
  knitr::kable(
    booktabs = TRUE,
    caption = 'Foo'
)
```

# References

Where the content of data.csv is

Reference,Classification
[@liuAdvancesDeepLearning2021],Yes

bookdown::render_book(".", "bookdown::html_document2") will create the HTML document as expected.

For reference, Bookdown will create the intermediate Markdown file:

<!--chapter:end:mwe.Rmd-->

bookdown::render_book(".", "bookdown::pdf_book") will fail to create the PDF document with the following error message:

Error: LaTeX failed to compile _main.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See _main.log for more info.
Please delete _main.Rmd after you finish debugging the error.

The LaTeX document created by Bookdown has

\caption{\label{tab:unnamed-chunk-1}Foo}
\centering
\begin{tabular}[t]{ll}
\toprule
Reference & Classification\\
\midrule
[@liuAdvancesDeepLearning2021] & Yes\\
\bottomrule
\end{tabular}
\end{table}

I might be able to use Bookdown's Text Reference to work around this issue but it will increase the complexit of my project that have a couple of dozen references like this one.

Any suggestions?
