Cannot create pool, VM folder path error

I am trying to use Add-AutomaticLinkedClonePool but running into the following error:

Add-AutomaticLinkedClonePool : PowershellService::AddAutomaticLinkedClonePool FAILED, error=Could not find vm folder (or folder in use) at path: /Site/Desktops/PoolName. Could not find vm folder (or folder in use) at path: /Site/Desktops/PoolName

I have tried all of the following:

-VmFolderPath "/Site/host/Desktops/PoolName"

-VmFolderPath "/Site/host/Desktops/"

-VmFolderPath "/Site/Desktops/PoolName"

Any idea what I'm doing wrong or where I should look next? I thought it might be a permissions issue but it seems rather unlikely as the account I'm using should have full privileges. As an aside, did you know that "Could not find vm folder" gets 0 results on Google?
