  • js code start call render

     window._waitRendPdftoStart_ = 0; //call most early
    
    
     window._waitRendPdftoStart_ = 1; //  call start render; timeout 20 s
    
    

tips

• use dumb-init to start docker container to avoid zombie chrome process (https://github.com/GoogleChrome/puppeteer/blob/master/docs/troubleshooting.md#running-puppeteer-in-docker)
