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

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'
)

As mentioned by @kopaczew, reverting the azure_storage_blob to 12.6.0 version fixed my issue. It does seem to be some sort of bug with the latest azure-storage-blob library. Unfortunately, the aforementioned issue is not limited to the create_container call. Answering my own question in case this helps someone else in a similar situation.

How I fixed my issue:

  1. Removed my previous venv environment (reinstalling itself caused some issues when importing the azure library)

  2. Created new venv

  3. pip install azure-storage-bob==12.6.0
