Folder name yy\xx was found with ID 0

Hi All,

I would like to change the environment of few folders and its documents. 

I'm using Brian's below blog as reference. 

Connection to PW datasource is successful. 

When i was running the command 

$folders = Get-PWFolders -FolderPath "Documents\Rendition testing" -JustOnce -Verbose 

I'm getting below error.

VERBOSE: Looking for folder 'Documents\Rendition testing'
VERBOSE: Folder 'Documents\Rendition testing' was found with ID 0
WARNING: 'Documents\Rendition testing' is not a valid folder name

Any suggestion would be helpful.

I'm using PowerShell ISE(x64) with pwps_dab version =
