Existing file marked as non-existing

What happened:

fs.isfile(existing_file_path) incorrectly returns False and gives a warning

EDIT: Output is

False
RuntimeWarning: coroutine 'AzureBlobFileSystem._details' was never awaited
RuntimeWarning: Enable tracemalloc to get the object allocation traceback

What you expected to happen:

Return True without a warning

Minimal Complete Verifiable Example:

import adlfs, fsspec, os
storage_options = {
    'account_name': os.environ['AZ_STORAGE_ACCOUNT_NAME'],
    'account_key': os.environ['AZ_STORAGE_ACCOUNT_KEY']    
}
az_storage_container_name = os.environ['AZ_STORAGE_CONTAINER_NAME']
fs = fsspec.filesystem('abfs', **storage_options)

base_path = f'abfs://{az_storage_container_name}/data/datasets'
existing_file_path = f'{base_path}/{dataset_id}'
fs.isdir(existing_file_path)

Anything else we need to know?:

• Continuation of https://github.com/dask/adlfs/issues/261 , with patched adfls and now on existing files (vs prev on non-existing)

Environment:

fsspec ‘2021.07.0’ (conda) adlfs ‘2021.08.1’ (pip, no conda yet) docker / ubuntu 18.04 / python 3.7

@lmeyerov – I just refactored _isdir on the accel_isdir branch. It passes all the tests, and completely eliminates the list_blobs call. Would appreciate your feedback if you have a chance to check it out.

Thanks for the help here @lmeyerov Release 2021.08.2 should fix the errors with isfile.
