How to fix ClientAuthenticationError when accessing the parquet (PyArrow) file through Blob Storage?

HI everyone

When I tried to build a blob client to access one .parquet file in Blob datastore with following script:

import os  
from azure.storage.blob import   BlobServiceClient  
import pandas as pd  
from io import BytesIO  

connection_str = "*****"
container = "*****"
blob_path = "./source/****.parquet"

blob_service_client = BlobServiceClient.from_connection_string(connection_str)
blob_client = blob_service_client.get_blob_client(container = container, blob = blob_path) 
stream_downloader = blob_client.download_blob()  #error happened here

stream = BytesIO() 
df = pd.read_parquet(stream, engine = 'pyarrow') 

It showed the following error message for this step:

blob_client.download_blob()

ClientAuthenticationError: Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature. RequestId:* Time:2024-03-20T20:40:44.8529867Z ErrorCode:AuthenticationFailed authenticationerrordetail:The MAC signature found in the HTTP request '****' is not the same as any computed signature. Server used following string to sign: 'GET

Could someone have a clue about this? Thank you
