Solved: Re: Error: CEF rendering exception - Qlik Community

Pavel_I · ‎2022-02-10

Dear Qlik Community,

I faced following issue when trying to add an img to my NPrinting report: Error: CEF rendering exception (attached is a screenshot of error popup). I've tested with different types of apps/objects/reports but always got the same issue. It is probably worth mentioning that there are no connection issues between Nprinting and Qlik Sense servers.

I know that this issue is often discussed here and i've also checked those articles:

https://community.qlik.com/t5/Knowledge/Nprinting-Log-ERROR-CEF-rendering-exception-GRPC-rendering/t...

https://community.qlik.com/t5/Knowledge/Advanced-troubleshooting-of-the-GRPC-and-or-CEF-Error-Issues...

but in none of the could find a solution for my case. I've checked cipher suites and both servers contain all required ones. Our both servers are in cloud and we found no issues with firewall or ports.

I would appreciate your support and thank you in advance.

Regards,

Pavel

Sorry for so many duplicated messages, somehow they didn't show up after I sent them and I thought they were not posted 🙂 Btw., I've restarted the NPrinting services and it resolved my issue. Thanks for help Frank and Ruggero. Hope I don't have to do it frequently. Any suggestions what was the issue in my case?

Kind regards,

Pavel

Hi Ruggero,

thanks for soon reply! I've checked it as well, but couldn't find any clue which might help to identify the problem. Maybe you could help?

That was the log file output regarding that issue:

Hi @Pavel_I

Important information about the error shown in the image you share is found in the NPrinting_cef_Engine.log.

Check that for time out errors. If you find SENSE_JS_RENDER_TIMEOUT or ErrorMaxJsAttemptsExceededResult or ERROR_RENDER_TIMEOUT_RESULT timeout errors, then you likely need to update your timeout settings as per the following article in the section near bottom of page Editing parameters in the renderer.config file

https://community.qlik.com/t5/Qlik-NPrinting-Discussions/Error-CEF-rendering-exception/m-p/1891590#M...

Additionally, you need to ensure you follow this article and update your NP server Internet settings

https://community.qlik.com/t5/Knowledge/NPrinting-Qlik-Sense-Images-Fail-to-Render-Export-Generate-o...

Finally,

If you are using 3rd party extensions then you might consider check if similar native qlik object work in place of the 3rd party objects/extensions.

@Pavel_I

Your logging does in fact specify "ERROR_RENDER_TIMEOUT_RESULT"

The solutions I shared should be checked and applied in your environment.

The articles give steps to apply the updates needed to hopefully resolve the issue.

Hi @Frank_S

I am following this thread, In our org nprinting set up, we do see this below log entry all the time in nprinting_engine_cef, but this doesn't impact the report generation. As of now we don't have dedicated Sense node for nprinting so slowness is the known factor but we get the needed output without any problem.

So my question is, do you see if I can resolve this below error and stop seeing in engine_cef log file using the steps you shared and would it give some benefits in terms of performance? ( We are on May 2021 Sense/Nprinting, everything works fine, its just these errors sometimes force me to think if I can get rid of them.)
