Problem

After importing a .ics file into Team Calendars, one of the warning messages below is shown. Some events (such as Jira Issue Dates, Jira Agile Sprints, or Jira Project Releases) do not display in your calendar.

Cause

NullPointerException in the server logs:

Unable to import events of type jira-project-releases
/confluence/plugins/calendar/importsubcalendar.action | traceId: 98d5540f729e61f6 | userName: admin | action: importsubcalendar
java.lang.NullPointerException

Workaround

Option 1. Import a .ics file from Team Calendars into Team Calendars.

Export from Team Calendars

• Select  to the right of the calendar and choose Export to iCalendar (so Team Calendars will apply its own formatting to the .ics file).

• Save the .ics file to your computer.

Import into Team Calendars

• Select  to the right of Add Calendar then choose Import Calendar.

• Enter the Name of the calendar and upload the .ics file you saved to your computer.

• Confirm if you can load the events of the calendar.

If the events still don't load, contact your admin to learn more from the server logs.

Option 2. Import a .ics file from Team Calendars into a third-party calendar.

In Team Calendars

• Select  to the right of the calendar and choose Subscribe.
• Select iCal and copy the Calendar URL. 

In a third-party calendar

• Go to your calendar app to set up a calendar using the Calendar URL you copied. Refer to your calendar app's documentation to find out how to add an iCal calendar.
