NetAppDocs doesn´t run in ONTAP 9.9.1P2

Hi guys,

I´m trying to cololect cluster data using NetAppDocs 3.7 (Latest available version) on a NetApp cluster version 9.9.1P2. Powershell starts to collect data but then displays the next error:

Write-Statistics : No se puede llamar a un método en una expresión con valor NULL.
En C:\Program Files (x86)\NetApp\NetAppDocs PowerShell
Module\NetAppDocs\Public\Format-NtapClusterData.ps1: 459 Carácter: 17
+ Write-Statistics @statsParams
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [Write-Statistics], RuntimeExcept
ion
+ FullyQualifiedErrorId : InvokeMethodOnNull,Write-Statistics

Firstly the out of date message is displayed:

ADVERTENCIA: The Hardware-ONTAP file is out of date. An update should be downloaded fro
m the NetAppDocs Community site and copied to the folder: C:\Program Files (x86)\NetApp
\NetAppDocs PowerShell Module\NetAppDocs\Resources

I suspect that the latest NetAppDocs version does not support ONTAP 9.9.1P2 I´m right? 

Please, could you help me? I can´t collect the output data and convert into a docx or excel file.

Thanks!
