Mailbox database recovery to alternate location

Question

Hi, i'm trying to write a script to automatically restore an exchange mailbox database to an alternate location
I am using
$pg = get-protectiongroup -dpmservername servername
$ds = get-datasource -protectiongroup $pg[2]; // 2's the index of the exchange protection group
$rp = get-recoverypoint -datasource $ds[2]; // 2's the index of the mailbox database
$gr = get-recoverableitem -recoverableitem $rp[rp.Length-2] -BrowseType child; // get second-last recovery point
$rop = New-RecoveryOption -targetserver lead.miningis.local -recoverylocation copytofolder -FileSystem -alternatelocation "C:\Ex2" -recoverytype restore -OverwriteType Overwrite
recover-recoverableitem -recoverableitem $gr -recoveryoption $rop
This results in powershell crashing.

Seems like a value was null. What am I doing wrong?
Thanks

I seem to also encounter this issue. Basically I am trying to do the same thing, automate a restore of a mailbox database to an offsite storage location for DR purposes. Seems to fail with the null error too. The only difference is I am using DPM 2012 R2
with Exchange 2013.
Here is my script:
$pg = Get-ProtectionGroup -DPMServerName "blah"
$ds = Get-Datasource $pg[3]
$rp = Get-RecoveryPoint -DataSource $ds[1]
$gr = Get-RecoverableItem -RecoverableItem $rp[-1] -BrowseType child
$rop = New-RecoveryOption -TargetServer "server name here" -TargetLocation "c:\Restorations" -RecoveryLocation CopyToFolder -Exchange -ExchangeOperationType NoOperation -RecoveryType Restore
Recover-RecoverableItem -RecoverableItem $gr -RecoveryOption $rop
Any help would be greatly appreciated!
Thanks
