Qlik NPrinting Unexpected CEF rendering exception with HTTP connection


  • NPrinting connectivity problems
  • In the Qlik NPrinting web console under 'Apps>Connections', if using "http://" rather than "https://" within your NPrinting Connections to Qlik Sense application(s), a metadata error similar to the one below may be encountered:
"Object DBbpbc of Sense app 7d789264-16f6-41b5-8dce-7670e779345f failed to render. ERROR: CEF rendering exception. GRPC rendering request failed ---> request with id 72de0741a840422ca95690ba27f2a750 failed with remote error ErrorGenericResult, task CEF_ON_JS_ERROR_MESSAGE_RECEIVED, result: ERROR_JS_FAILURE_RESULT, a JavaScript call failed, , last js call: qlikPrintingService.render("7d789264-16f6-41b5-8dce-7670e779345f","np17-1eb48465-0512-4ca6-9ff3-44ebfca8ba84","object","DBbpbc")"

Environments that may be affected:
  • Qlik NPrinting, April 2019 and earlier version when used with Qlik Sense September 2018 or higher.

  • Use HTTPS:// rather than HTTP:// in the NP connection Proxy Address field
  • Stop the NPrinting Engine service
  • On your NPrinting Engine computer(s), locate the file c:\Program Files\NPrintingServer\NPrinting\Engine\engine.config
  • Within the "appSettings" section of this config file, add a line <add key="webrenderer-mashup-qs" value="wssecure=1" />
  • Repeat process for each NP Engine if you have more than one NPrinting Engine installed
  • Restart your NPrinting Engine service.
