[noonenene]

from redis.cluster import RedisCluster as Redis
redis_userdb = Redis(host='xxx.yyy.zzz.xx', port=xxxx, password='password)
print(redis_userdb.get_nodes())

I able to write data on all cluster node without any issue but not able to run Migrator().run()

print(Users.get("user1"))
Migrator().run()
