Errors when importing from previously exported VMHost group

[mtboren]

Opening new issue from comment from user @gillx0101 (original comment here)

Can someone help! I'm able to use the export-drsrule successfully, but get errors when importing the txt file with the following;

Get-DrsRuleObject : Cannot validate argument on parameter 'Object'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again. At C:\Program Files\WindowsPowerShell\Modules\DRSRule\2.0.0\DRSRule.psm1:1572 char:38

CategoryInfo : InvalidData: (:) [Get-DrsRuleObject], ParameterBindingValidationException
FullyQualifiedErrorId : ParameterArgumentValidationError,Get-DrsRuleObject
I am using Powercli VMware PowerCLI 11.3.0 build 13990089 and verion 2.0.0 of the DRSRule.

I am testing with vcentre 6.7, creating a test VM/Host group, exporting out then deleting from vmware and trying to import back in from the export file. Any pointers would be appreciated.>

Hello, @gillx0101

A few things to help us understand what might be happening here:

• I take it you are on PowerShell 5.* -- is that fact? (What is the PowerShell version you are using)
• Are we able to do a dry run using the -ShowOnly parameter on the Import-DrsRule invocation that you are making? If so, what is the result?
• What happens when you try to import just the given DrsVMHostGroup by using the -Name parameter on the Import-DrsRule invocation that you are making?

Thanks @mtboren for taking a look. I am using a Windows 10 client with PS 5.1 installed. Below is the output running with the "ShowOnly" switch

PS C:\WINDOWS\system32> Import-DrsRule d:\temp\drs.txt -ShowOnly
Method invocation failed because [System.Management.Automation.PSCustomObject] does not contain a method named
'GetEnumerator'.

Not sure if I follow your last point? I created a VM Host Group with a name "DRSHost", but when I tried to export got the following:

PS C:\WINDOWS\system32> Export-DrsRule -Name DRSHost

cmdlet Export-DrsRule at command pipeline position 1
Supply values for the following parameters:

    + CategoryInfo          : InvalidOperation: (DRSRule_VMToVMRule:TypeName) [], RuntimeException

I think its worth noting I also get the above intermittently when just running an export-drsrule and providing a path for the output ??
