How fix no basic auth credentials error wit hdockerpy and aws ecr repo?

Question

I m trying to execute the folowing python code:

import logging
import sys
import docker, boto3
from base64 import b64decode

logging.basicConfig(stream=sys.stdout, level=logging.INFO)

LOCAL_REPOSITORY = '111111111111.dkr.ecr.us-east-1.amazonaws.com/my_repo:latest'

image = '111111111111.dkr.ecr.us-east-1.amazonaws.com/my_repo'
ecr_registry, _ = image.split('/', 1)
client = docker.from_env()

# Get login credentials from AWS for the ECR registry.
ecr = boto3.client('ecr')
response = ecr.get_authorization_token()
token = b64decode(response['authorizationData'][0]['authorizationToken'])
username, password = token.decode('utf-8').split(':', 1)

# Log in to the ECR registry with Docker.
client.login(username, password, registry=ecr_registry)
logging.info("loggined")
client.images.pull(image,   auth_config={
  username: username,
  password: password
})

And got exception:

C:\myPath>python app/pull_example.py
INFO:botocore.credentials:Found credentials in environment variables.
INFO:root:loggined
Traceback (most recent call last):
  File "C:\Python3\lib\site-packages\docker\api\client.py", line 261, in _raise_for_status
    response.raise_for_status()

During handling of the above exception, another exception occurred:

    password: password

What is the problem? Why I can not pull image even after client.login call which happens wihtout any exeptions. What is the correct way to perform login and pull image from ECR repository and dockerpy?

This was happen due to - https://github.com/docker/docker-py/issues/2157

Deleting ~/.docker/config.json fixed the issue.
