Object reference not set to an instance of an object

[jevao]

I receive the following error when running:

Start-VBRRestoreVM -RestorePoint $RestorePoint -Server $Server -ResourcePool $ResourcePool -Datastore $vmdatastore -VMName $vmsin1

Code: Select all

Start-VBRRestoreVM : Object reference not set to an instance of an object.

    + FullyQualifiedErrorId : System.NullReferenceException,Veeam.Backup.PowerShell.Command.StartVBRRestoreVM

I used the following to set this up:

Code: Select all

 $RestorePoint = Get-VBRRestorePoint -Backup $bkup -Name $vmname-string  | sort-object $_.creationtime -Descending | select -first 1
$vmdatastore = find-vbrvidatastore -server spock.das.perforce.com -name $vmds
 $ResourcePool =  Find-VBRViResourcePool -Server (get-vbrserver -name $servername) | select -last 1
$Server = Get-vbrserver -name $servername
$vmsin1 = "vmname"

Any help would be greatly appreciated.

As first investigation step I would double check whether all variables have been assigned properly. Input variables in PowerShell console and see whether they do contain not null value.

Code: Select all

$RestorePoint
$vmdatastore 
$ResourcePool
$Server
$vmsin1 

Thanks.

Thanks for replying.
Yes I did that.
I ran it through the shell and saw the output of each was an object.
The only thing that seemed strange was "get-vbrserver -name" did not return multiple properties in the object,
but just the server name.
Other than that, if I reduce the paramaters to only mandatory parameters, Restorepoint and Server, I still see the error.

I was trying to restore to a cluster, not a host.
When I changed to restore directly to a host I receive the following error:

Start-VBRRestoreVM : Exception has been thrown by the target of an invocation.

SOLVED:
The "Exception thrown" error was due to not running as Administrator.
Once I did restore from host, rather than cluster, and "Run as Administrator" on console2,
then it worked fine.
Thanks much for your help.

Yes, that was the second question that I was going to ask - whether or nor the used account has required permissions. Glad that you've nailed it yourself. Thanks.
