Hello, I'm having a strange error while locating the FileStore folder on DBFS.

Following the error message:

dbutils.fs.ls('dbfs:/Filestore')

java.io.FileNotFoundException: File /6239660819762462/Filestore does not exist.
 
ExecutionError                            Traceback (most recent call last)

The code '6239660819762462' seems to be the WorkspaceId where the Notebook is.

Can anyone explain me why that happen? Thanks
