Unable to setRecoverySettings over the SRM API with powerCLI

Hello all,

I am create script for automation of adding server into SRM with requested settings, like priority, postRecoverySteps and so on.

I am strugled in the last step to set the requested settings to the SRM plan over a method srmPlan.SetRecoverySettings(vm, settings) with the following error:

Exception calling "SetRecoverySettings" with "2" argument(s): "fault.drextapi.fault.InvalidArgument.summary"

At C:\PowerShell\srm\SRM-Cmdlets\SrmFunctions.ps1:726 char:3                                               

+         $RecoveryPlan.SetRecoverySettings($moRef, $RecoverySettings)

    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
