Error sending information to the bank. Editing Form

I have an edit form for a posts feed. When I click to save the edit the following error appears:

SQLSTATE[23502]: Not null violation: 7 ERROR: null value in column "title" 
violates not-null constraint
DETAIL: Failing row contains (1, 1, null, null, null, 2018-04-24 10:04:55). 
(SQL: update "feeds" set "title" = , "description" = , "updated_at" = 2018- 
04- 24 10:04:55 where "id" = 1)

It's as if you're sending information in white, but there's nothing blank.

       $feed = feed::find($idFeed);
       $feed->description = $description;
