Test-NcExportAccess commandlet not working with ONTAP 8.3.2P2 or 9.1P5

Has anyone succesfully used the Test-NcExportAccess commandlet? This functionality is very useful on the commandline, but would be even more so if I could access this through powershell. The full error given when run is:


Test-NcExportAccess : Unable to find API: export-check-access-get-iter
At line:1 char:1
+ Test-NcExportAccess
+ ~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (dc2-dot:NcController) [Test-NcExportAccess], EAPINOTFOUND
    + FullyQualifiedErrorId : ApiException,DataONTAP.C.PowerShell.SDK.Cmdlets.Exports.TestNcExportAccess

It appears that the API is missing? I've tested this on two different clusters, one running ONTAP 8.3.2P2 the other running ONTAP 9.1P5 same error on both clusters. Any ideas?
