fsspec_wrapper.core.AzureBlobFileSystem(...).exists("x") raises Value Error "name length is not within the permissible limits"

Reproduce the abfss case with Azure Synapse and exists("x") first. Then read adlfs/spec.py around _exists and _container_exists, along with the fsspec_wrapper/core.py hook shown in the traceback. Done means a missing short path returns False instead of raising the resource-name ValueError.

3.8.10 | packaged by conda-forge | (default, May 11 2021, 07:01:05) \n[GCC 9.3.0]
Name: fsspec Version: 2021.6.1

1. Open Azure Synapse,
2. Create python notebook
3. Execute the following code cell below
4. Expect result to be False
5. instead ValueError is raised

import fsspec
filesystem = fsspec.filesystem(
    protocol    = f"abfss",
    account_url = f"abfss://{STORAGE_ACCOUNT}.dfs.core.windows.net/"
)
filesystem.exists("x")
