cursor dictionary and named_tuple parameter do not work anymore

import mariadb

conn_params = {"user": "root", "password": "xxx", "host": "localhost", "database": "myDB"}

connection = mariadb.connect(**conn_params)

# cursor = connection.cursor(named_tuple=True)

cursor = connection.cursor(dictionary=True)

cursor.execute("SELECT field FROM myTable")

rows = cursor.fetchall()

print(rows)

# will print list of tuples without field names
