Generate PDF Report Fails

Elastic Stack Kibana
1

Hello,
I have checked previous posts but still cannot find a solution.
Kibana/Elastic version - 7.9.1
5 Elastic nodes
2 Kibana nodes
Platinum licenses

When I try to generate a pdf report, it fails.
I also have a standalone test env, and there the pdf function works well.

Appreciate your guidance and advise.

The errors I see in Kibana logs

Most likely all the needed dependencies are not installed on the server you are running Kibana on See here

Checking with rpm -qa or yum list installed shows none of the packages are installed.
However, the same results on my test environment (where pdf reports work well)
So, how can I check if I am missing these packages or it is something else? i.e. wrong configurations/settings?

That usually means it can not find the required dependencies, I would run through the installs whether they are reported missing or not.

You can also set kibana logs to verbose.

logging.verbose: true
