Agile Sprint Planing Tab is not working

Upon migration from Agile 1.0 to 2.0, "Sprint Planning" tab is unresponsive

Any Patch

While we click on the "Sprint Planning" tab, we can see the below error in the browser console,

 {"error":{"message":"Cannot convert null to an object.","detail":"TypeError: Cannot convert null to an object. (sys_script_include.d8db4ec05b26030036c32c1cf0f91aca.script; line 22)"},"status":"failure"}

In the script include "SprintPlanningMetaDataService" we see that the below line of code checks for the Planned Start/End dates on the Sprint,

                  var startDate = sprint.start_date.getGlideObject().getLocalDate().getDisplayValue();

                  var endDate = sprint.end_date.getGlideObject().getLocalDate().getDisplayValue();

The above script basically do a glide record on the rm_sprint that is "Sprint" table and check if a sprint associated to an Agile group has the planned start/end dates while displaying the content.

Entering the Planning Start/End dates for the Sprints associated to an Agile group would fix the issue.
