Cache Exception viewing Requirements - com.atlassian.cache.CacheException

Hi!

We get some errors when viewing and editing certain issues in our JIRA instance after we upgraded the X-ray plugin.

When I see the logs I can see there exception is triggered by an X-ray Rest method: /rest/raven/1.0/requirement/TIM-216/status

We didn't had this problem before the upgrade.

I have also seen that this error exception is only triggered by issues in a certain project and certain state (only in project "TIM" and status "In Review").

We cannot edit the issues that is triggered by this exception.

This is the exception we get when viewing the issue:
