/projects.html not working in AEM 6.1

[cq_5_5]

We are in process of upgrading my AEM 6.0 instance to 6.1. After running upgrade, I'm getting following exception while accessing projects.html.

Did you follow all the AEM 6.1 upgrade docs:

https://docs.adobe.com/docs/en/aem/6-1/deploy/upgrade.html

[cq_5_5]

Yes, we have followed the steps mentioned. I was able to access the page once and then it stopped working automatically and now i getting this error consistently.

From the logs, i'm not getting any clue about what has caused this.

[smacdonald2008]

THis looks like some sort of bug in your development environment. For the best route to get this resolved - file a support ticket.

I am sorry to hear about this issue.

Log in using a different user and see if you still see this exception. From the stacktrace, it seems that one of the workflow instances in your AEM instance has a very long description because of which the XSS API is failing. Try to find that instance and terminate it and see if you get rid of this exception. Else, you can try bumping the input size limit in /apps/cq/xssprotection/config.xml (overlay it from  /libs/cq/xssprotection/config.xml ) - <directive name="maxInputSize" value="200000"/>
