Trying to export a dashboard from OC is failing with Not able to generate PDF:
This happens with any type of dashboard, and regardless of where it is exported from.
This is known to happen with RH Linux 8.4 and 8.5, and was related to a 3rd party component tied to these releases.
Release : 20.3

Fixed in 20.4 + CU2
