      Description

      When the cast expression is applied on empty string "" to cast it to interval type it throws Null pointer exception..

      Getting the same exception when I tried reproducing the same through test case
      checkEvaluation(Cast(Literal(""), CalendarIntervalType), null)

      Exception i am getting is:
      java.lang.NullPointerException was thrown.
