'HTTP headers is not in the correct format' error when creating Azure Container using Python SDK

Question

I'm trying to create an Azure blob container using Python SDK with the below code. I'm getting an 'ErrorCode:InvalidHeaderValue' in the response.

I'm using the 'ConnectionString' from 'Access Keys' section from the Azure Portal of the storage account. And I don't think the connection is the issue since this line works ok blob_service_client = BlobServiceClient.from_connection_string(connection_string).

I used a clean venv for this and below are the library versions azure-core==1.10.0 azure-storage-blob==12.7.1

import os
import yaml
from azure.storage.blob import ContainerClient, BlobServiceClient

def load_config():
    dir_root = os.path.dirname(os.path.abspath(__file__))
    with open (dir_root + "/config.yaml", "r") as yamlfile:
        return yaml.load(yamlfile, Loader=yaml.FullLoader)

config = load_config()
connection_string = config['azure_storage_connectionstring']

blob_service_client = BlobServiceClient.from_connection_string(connection_string)
blob_service_client.create_container('testing')

Traceback (most recent call last):
  File "/Users/anojshrestha/Documents/codes/gen2lake/project_azure/lib/python3.7/site-packages/azure/storage/blob/_container_client.py", line 292, in create_container

You do not need to reinstall. You can get around this issue by setting your api_version variable when instantiating any of the clients.

For example:

blob = BlobServiceClient(
    account_url="https://MY_BLOB_STORAGE.blob.core.windows.net",
    credential="MY_PRIMARY_KEY",
    api_version="2019-12-12", #or api_version='2020-02-10'
)
