Uncaught Problem handling the request- AEM 6.5- SP 6.5.15

[Kumar001]

Hello,

I have setup the author instance and upgraded the SP to 6.5.15 and then after installed the custom code.
As soon as deployment is done instance is breaking totally and it is throwing "Uncaught Problem" in logs.

Also when trying to land on any page on instance like crx or welcome page throwing the "HTTP ERROR 500"
Attached the screenshot for the UI side



Can some one help on how/what to troubleshoot?

@Kumar001 Could you please check ACS Commons bundle is active?

[Kumar001]

Thank you your question and that fixed the issue.
But, just curious what made you to ask it?

[Saravanan_Dharmaraj · Accepted solution]

@Kumar001 Versioned Clientlibs functionality is from ACS Commons. Error is for the same.

https://adobe-consulting-services.github.io/acs-aem-commons/features/versioned-clientlibs/index.html 

If the bundle is not active, you will see the blank page.
