[Ultimate PDF] Ultimate PDF Error - "Execution context was destroyed, because of navigation"
Reactive icon
Forge component by Leonardo Fernandes


We are having a issue in Ultimate PDF when trying to generate a single PDF. Last week, It's working but unfortunately it doesn't work now and generate an error. There were no changes in the environment prior this issue.

Please see attached error message in screenshot.

The main message is "Execution context was destroyed, most likely because of navigation"

I'm thinking the issue is from Pupeteer Node Library and having an issue inside of it? Haven't seen anyone encountered it before in Outsystems Ultimate PDF.

Thank you



Hi John,

Could you access https://app-test.med.hku.hk/HKUAdminPortal/StudentInformation_PDF?StudentInformationId=63?

Please check if you can access the URL or not first. I think you recognize the issue probably but the community will help you if you can give some more details after your check. 

Best regards,

Hi Necmettin,

Thank you for responding. When I try to access the URL from the PDF. I was able to access it in browser and render the PDF. But when trying to generate using Ultimate PDF, it throws this kind of error

Hope this helps



Hi John.

Is this error happening with any PDF? Or only with some specific PDFs?

Could you install the management app and download the troubleshooting zip file? Install the management app from here: https://www.outsystems.com/forge/component-overview/11585/ultimate-pdf-management


I'm facing the same issue, but only in one environment. It works fine in DEV and UAT, but the same app version doesn't work in STG.

Any idea about this?
