Redis cluster Migrator not working

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()

ResponseError: Unknown Index name

The report names RedisCluster and Migrator().run(), but no repository file or test. Start by reproducing the failure with the shown cluster setup, then trace Migrator and RedisCluster command routing around the Unknown Index and MovedError responses. Done means migration completes on a Redis cluster without these errors, with a regression test covering the case.
