Jira Issues Calendar 400 (Internal Server Error)

[Amal Thomas]

I am creating a new Dashboard using the JIRA Issues Calendar.  I have 2 Calendar Gadget setup.  One tracks Releases.  The other tracks Requests.  The Release one works perfectly.  However, when setting up the Request Calendar, it always returns a “400 (Internal Server Error).”  I tried a few different filters and tracked it down to any time the filter includes an Issue that is the Request type, the gadget will error.  We are using the Request type to track PS requests for Hotfixes, so we need this calendar.

Note : It is fixed after reindexing/restarting Jira, but this happens every week
