Kibana 7.5.2 fails to generate Reports with Network Plugin

We have a standalone (no proxies) Elastic and Kibana 7.5.2 deployed in RHEL 7.X, and Network 7.5.2 plugin is working as expected.

However, when you try to Share any Dashboard with Network Plugin Visualization object as PDF / PNG Reports in Chrome browser, after 3 attempts it fails with error "Unable to generate report" in Management > Kibana > Reporting.

Our Kibana config:

[..]
xpack.reporting.queue.timeout = 2-5 mins
[..]

Hope someone else will also run into this same issue.

Please note that Dashboards without Network plugin were generated fine.

Reproduce the failure in Kibana 7.5.2 on RHEL 7.X using Chrome, a dashboard containing a Network Plugin visualization, and PDF or PNG reporting. Compare this with a dashboard without the plugin and inspect the Reporting failure after three attempts; done means the Network visualization report generates successfully.
