Version too old. Try to reproduce it using the latest 
version: https://github.com/jgm/pandoc/releases/latest There's various way 
to install it, e.g. you can just unzip pandoc-2.9.2.1-linux-amd64.tar.gz 
and put pandoc and pandoc-citeproc to somewhere in your path, such as 
~/.local/bin

(To take one more step you can go to the GitHub Action to download the 
latest nightly build to make sure the problem has not been solved yet.)

In general you'd want to ensure the problem has not been solved yet, and to 
do that you want the latest version, which unfortunately in distros with 
package manager can be a big problem because people often just use the one 
from there, which is too old especially from Ubuntu.
