Record View Fails when we go to Feed view

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.
