ProgrammingError :No results. Previous SQL was not a query

Question

As I'm getting output in SQL when I try in python its showing as ProgrammingError :No results. Previous SQL was not a query. even I have tried with fetchone() and fetchvalue()

here what I tried

@api_view(['GET'])       
def getUtilizationSummary(request, UserId):

    if request.method == 'GET':
    
        cursor = connection.cursor()
        cursor.execute('EXEC [dbo].[Usp_Leftsidepanel] @UserId=%s', (UserId,))
        result_set = cursor.fetchall()
        
        print('getUtilizationSummary', result_set[0])
        data = []
        for row in result_set:
            data.append({
                'Utility':row[0],
                'Productivity':row[1],
                'BreakMeeting':row[2]
            })
        return Response(data)
