Record View Fails when we go to Feed view

Question

Hi All, 
 
 I am facing a strange issue.In record, I have feed view which was working fine, but Suddenly it starts throwing Error. When I checked the issue ,I come to know that they is a manual entry in the table which was null , and sorting was put on that field for record View. 
 
 Even when I tested the Query entity , it is able to fetch the data and gives proper result but when it is mapped to Feed view it gives error due to that null value as sorting was put on that column ,So when I just change the view from Feed to List ,with the same Sorting column the same is working fine . 
 Can any one help me understand why their is such dependency on Feed view.

Hi manishk0001 make sure, the record feeds related data must not be deleted. Because feed works on top of record identifier which is nothing but the primary key value of the row of your record through the context of this feed was posted. If so you will face this kind of issues.
