Issues using New-SCSMObjectProjection cmdlet

Question

Hi all,
I'm currently creating a workflow which creates assets (Provance) in the CMDB based on an attached XLS file. Since we want to populate as much infomation during the creation as possible, I have to work with projections to specify information such as Location,
Owner, Cost Center, etc.. Reading the data from XLS and making up the variables etc. is working fine, I'm just stuck with actually creating the projection itself. I've used this blog post as a reference for my script:http://blogs.technet.com/b/servicemanager/archive/2013/01/16/creating-membership-and-hosting-objects-relationships-using-new-scsmobjectprojection-in-smlets.aspx
The issue is that I get an error message saying "FullyQualifiedErrorId : Alias not found on projection,SMLets.NewSCSMObjectProjectionCommand". I get this error for all projection components I've specified in my projection object.
Here's the exact error code
New-SCSMObjectProjection : CostCenter
At line:19 char:43
+ $CurrentHWAsset = New-SCSMObjectProjection <<<< -Type $AssetProjection -Projection $ProjectionObject -passthru
+ CategoryInfo : NotSpecified: (CostCenter:String) [New-SCSMObjectProjection], ObjectNotFoundException
+ FullyQualifiedErrorId : Alias not found on projection,SMLets.NewSCSMObjectProjectionCommand
New-SCSMObjectProjection : Owner
At line:19 char:43
+ $CurrentHWAsset = New-SCSMObjectProjection <<<< -Type $AssetProjection -Projection $ProjectionObject -passthru
+ CategoryInfo : NotSpecified: (Owner:String) [New-SCSMObjectProjection], ObjectNotFoundException
+ FullyQualifiedErrorId : Alias not found on projection,SMLets.NewSCSMObjectProjectionCommand
New-SCSMObjectProjection : Organization
At line:19 char:43
+ $CurrentHWAsset = New-SCSMObjectProjection <<<< -Type $AssetProjection -Projection $ProjectionObject -passthru
+ CategoryInfo : NotSpecified: (Organization:String) [New-SCSMObjectProjection], ObjectNotFoundException
+ FullyQualifiedErrorId : Alias not found on projection,SMLets.NewSCSMObjectProjectionCommand
New-SCSMObjectProjection : CatalogItem
At line:19 char:43
+ $CurrentHWAsset = New-SCSMObjectProjection <<<< -Type $AssetProjection -Projection $ProjectionObject -passthru
+ CategoryInfo : NotSpecified: (CatalogItem:String) [New-SCSMObjectProjection], ObjectNotFoundException
+ FullyQualifiedErrorId : Alias not found on projection,SMLets.NewSCSMObjectProjectionCommand
New-SCSMObjectProjection : Location
At line:19 char:43
+ $CurrentHWAsset = New-SCSMObjectProjection <<<< -Type $AssetProjection -Projection $ProjectionObject -passthru
+ CategoryInfo : NotSpecified: (Location:String) [New-SCSMObjectProjection], ObjectNotFoundException
+ FullyQualifiedErrorId : Alias not found on projection,SMLets.NewSCSMObjectProjectionCommand
Obviously the error message is quite specific saying that the alias doesn't exist, I just don't know why it's throwing that error message because the alias cleary exists as the following Screenshots proves it.
I even exported the MP and checked the projection component aliases in the MP and they really do exist.
This is the part of my PowerShell code where I'm defining the projection object:
$AssetProjection = Get-SCSMTypeProjection Provance.ITAM.HardwareAssetProjection$$HWAssetProjection = @{__CLASS = "Provance.ITAM.HardwareAsset";
__OBJECT = @{"Id" = "HW{0}";
"AssetTag" = "$AssetTag";
"SerialNumber" = "$AssetSerialnumber"}
CatalogItem = @{__CLASS = "Provance.ITAM.HardwareCatalogItem";__SEED = $HWModel}
Owner = @{__CLASS = "System.User";__SEED = $AssetOwner}
Location = @{__CLASS = "Provance.ITAM.Location";__SEED = $AssetLocation}
Organization = @{__CLASS = "Provance.ITAM.Organization";__SEED = $AssetOrganization}
CostCenter = @{__CLASS = "Provance.ITAM.CostCenter";__SEED = $AssetCostCenter}
}$CurrentHWAsset = New-SCSMObjectProjection -Type $AssetProjection -Projection $ProjectionObject -passthru
As you can see I'm intending to just create the asset itself. CatalogItem, Owner, Location, Organization, and Cost Center already exist in the CMDB and shall just be related to the newly created asset, that's why I'm using the __SEED Definition.
I'm really having a hard time troubleshooting this with the given error message. Does anyone see what I'm doing wrong and can help me poor guy out here? :)
Thanks in advance
Cheers

I am actually struggling with the same kind of problem at the moment. Did you figure it out? 
I've tried using New-SCSMObjectProjection -Type "type projection" instead, but this yield another error:
New-SCSMObjectProjection : Object reference not set to an instance of an object.
Here is my script:
#Get Service Owner User
$Owner = Get-SCSMObject -Class (Get-SCSMClass System.Domain.User$) -Filter "UserName -eq mom"
#Create New Business Service via TypeProjection
$bsTypeProjection = @{ __CLASS = "Microsoft.SystemCenter.BusinessService";
__OBJECT = @{ "DisplayName" = "Test Business Service - Created via PS"
"Notes" = "Notes 123"
"ServiceId" = ([guid]::NewGuid()).ToString();
ComponentServiceOwners = @{ __CLASS = "System.User";
__SEED = $Owner
}#/Service Object
New-SCSMObjectProjection -Type Microsoft.System.Service.FormProjectionType -Projection $bsTypeProjection -bulk
It works if I don't have ComponentServiceOwners, and if I use your method by declaring the typeprojection first, it gives the error: Alias not found
