sasl.process() fails

[Pustik41]

I try to connect to HDFS via AutoConfigClient, but have an error:
File "/mnt/kubernetes/sandbox/data-governance--change-control-statistics-reporter/lib/python3.6/site-packages/snakebite/rpc_sasl.py", line 109, in connect initiate.token = self.sasl.process() TypeError: None has type NoneType, but expected one of: bytes [in /mnt/kubernetes/sandbox/data-governance--change-control-statistics-reporter/lib/python3.6/site-packages/cmdlineutil/__init__.py:230, 140396487395136 (MainThread), 104 (MainProcess)]

Additional info i use client.ls(["/"]) and it returns generator object HAClient._ha_gen_method..wrapped, but if I put it in list list(client.ls(["/"])) get this error
