Issue script & Debug output

import os
from azure.identity import DefaultAzureCredential
from azure.storage.blob import BlobServiceClient

Replace with your actual storage account name

account_url = "https://.blob.core.windows.net"
credential = DefaultAzureCredential()

Create the BlobServiceClient object

blob_service_client = BlobServiceClient(account_url, credential=credential)

print(blob_service_client)

def download_blob_to_file(blob_service_client: BlobServiceClient, container_name: str, blob_name: str, download_file_path: str):
try:
# Get the blob client
blob_client = blob_service_client.get_blob_client(container=container_name, blob=blob_name)

    # Ensure the directory exists
    os.makedirs(os.path.dirname(download_file_path), exist_ok=True)
    
    # Download the blob and save it locally
    with open(file=download_file_path, mode="wb") as file:
        download_stream = blob_client.download_blob()
        file.write(download_stream.readall())
    print(f"Blob '{blob_name}' downloaded successfully to '{download_file_path}'.")
except Exception as ex:
    print(f"Error downloading blob: {ex}")

Call the function

download_blob_to_file(blob_service_client, container_name="car", blob_name="RAV4.pdf", download_file_path=r"pdf/p1.pdf")

Expected behavior

Downloaded file from Blob Storage

Hi @rakshahulle, from your provided info, it seems like an issue when using the Azure Python SDK, please raise an issue here instead as we are not sure about the authorization details in the SDK, thanks. https://github.com/Azure/azure-sdk-for-python/issues/new?template=bug_report.md
