ERROR: CEF rendering exception. GRPC rendering request failed, error: One or more errors occurred..  

Environment:

  • Qlik NPrinting June 2018
  • Qlik NPrinting April 2019 
  • Qlik NPrinting September 2019 

 

Cause:


This error may have occurred because of some orphan processes named reporting_web_renderer. This may have resulted from an unexpected engine crash.

 

Resolution:


A possible workaround could be to kill the engine process and then kill any subprocess called reporting_web_renderer in task manager. Alternatively, restart the server where the NPrinting Engine service is installed.
