With the new Module 9.11 or with the lastest 9.12 I got the error if I want to browse a volume

PS C:\Temp> Connect-NcController -Name $cluster -Credential $cred -ZapiCall

Is this a BUG ? With the old module, like 9.8 it works perfect. And yes. With a directory it works. But I want to browse the volume.

If it works with the raw API of the same ONTAP version but not different Powershell module version, then it's certainly a bug in the later version of the powershell module.

I actually had to refactor a function to use this instead of the excessively slow VMware *-datastoreitem functions...

#

Let me collect some info around my test...

oof, I'm using module version 9.10.1.2111

Let me update and try again...

After updating the PowerShell module to 9.12.1.2302 I was no longer able to connect to my ONTAP 9.7P13 cluster... Unsure this is just too many versions apart or someone changed something because I was getting an access denied which is typically not an issue with the module. Either way, rolling back versions one at a time until I can connect or if still not able to connect when back at my original version, then it's not PowerShell and is officially something else.
