BigTemplate pdf export does not work due to problem with SSL certificate.

If logs contain errors like this:

// -------------------------- Shell output --------------------------
ERROR! Error: net::ERR_SSL_CLIENT_AUTH_CERT_NEEDED
at navigate (/usr/lib/node_modules/puppeteer/lib/Page.js:526:37)
at <anonymous>
at process._tickCallback (internal/process/next_tick.js:189:7)
// -------------------------- Shell output --------------------------

The old puppeteer version might cause it.

To fix this, upgrade puppeteer by executing the command below on the server with your Jira instance:

sudo npm -g update puppeteer --unsafe-perm=true
