Describe the bug

When placing .. into the path, I get blob properties, can create files, etc., just fine, but I cannot list the directory.

To Reproduce

account_name = "REDACTED"
account_url_dfs = f"https://{account_name}.dfs.core.windows.net"
container_name = "tmp"
blob ='test/../test/test2/'

credential = get_azure_credential()
fsc = DataLakeServiceClient(account_url=account_url_dfs, credential=credential).get_file_system_client(container_name)
properties = fsc.get_file_client(blob).get_file_properties()
fsc.create_file(f"{blob}file.txt")

# This line fails with `azure.core.exceptions.ResourceNotFoundError: The specified path does not exist.` 
paths = list(fsc.get_paths(blob))

Expected behavior
I am expecting to get list of files or directories from given directory

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @jalauzon-msft @vincenttran-msft.

Hi @lejmr, I had made a previous comment but just deleted it as it had some incorrect information that I was not aware of. We did some testing on this and basically concluded that the Storage service does not seem to support the .. part of the path as expected. It treats it as part of the path rather than transitioning up a directory as other operations do.

Unfortunately, given that, there is not much we can do from the client side. I will try to check with the service team to see if this is expected, but it's not likely they would be able to change this any time soon.
