26D Debrief Critical Error

Summary:

We are Testing Fusion Field Service. While using Debriefing in 26D we are getting an error :

{ "title" : "Bad Request", "status" : "400", "o:errorDetails" : [ { "detail" : "You must enter at least 3 characters in 1 of these fields: ItemNumber,ItemDescription,Keyword. (EGP-2776109)", "o:errorCode" : "EGP:::EGP_ONE_FIELD_THREE_CHAR_ERR" } ] }

This was working till last week in 26C. New issues have shown up with Debriefing in 26D. Please suggest.
