mounting point in azure databricks

I would like to use a mount point on azure databricks with this code:

dbutils.fs.ls('/mnt/dz/')

but i have this error

shaded.databricks.org.apache.hadoop.fs.azure.AzureException: java.util.NoSuchElementException: An error occurred while enumerating the result, check the original exception for details.

what should i do in this situation?

i have create a mounting point with this code

mountPoint = "/mnt/dz/"
if not any(mount.mountPoint == mountPoint for mount in dbutils.fs.mounts()):
  try:
    dbutils.fs.mount(
      source = "wasbs://{}@{}.blob.core.windows.net".format(blobContainerName, storageAccountName),
      mount_point = mountPoint,
      #extra_configs = {'fs.azure.account.key.' + storageAccountName + '.blob.core.windows.net': storageAccountAccessKey}
      extra_configs = {'fs.azure.sas.' + blobContainerName + '.' + storageAccountName + '.blob.core.windows.net': sasToken}
    )
    print("mount succeeded!")
  except Exception as e:
    print("mount exception", e)

the code have run well, but now

dbutils.fs.ls('/mnt/dz/')

is not working

shaded.databricks.org.apache.hadoop.fs.azure.AzureException: java.util.NoSuchElementException: An error occurred while enumerating the result, check the original exception for details

while creating sas token in permissions select list option:
