ValueFromPipelineByPropertyName failing on module cmdlet - powershell

Question

I have a cmdlet called Get-Organization which returns the below as return type
public class OrgModel
{
public string OrgName {get;set;}
}
[Cmdlet(VerbsCommon.Get, "Organization")]
[OutputType(typeof(OrgModel))]
public GetOrganizationCmdlet : PSCmdlet
{
[Alias("OrgName")]
[Parameter(Mandatory = true, ValueFromPipelineByPropertyName = true, Position = 0, HelpMessage = "The orgname.")]
string Name{get;set}
...
}
I have another cmdlet called Department which returns a model DepartmentModel. Get-Department -OrgName <somename> returns all departments inside the Orgname. The cmdlet is defined as below.
[Cmdlet(VerbsCommon.Get, "Department")]
public GetDepartmentCmdlet : PSCmdlet
{
[Parameter(Mandatory = true, ValueFromPipelineByPropertyName = true, Position = 0, HelpMessage = "The org name.")]
[ValidateNotNullOrEmpty]
string OrgName {get;set}
[Parameter(Mandatory = false, ValueFromPipelineByPropertyName = true, Position = 1, HelpMessage = "Optional. The department name.")]
string Name{get;set}
...
}
After loading the module, everything works as expected. The place where it breaks is piping. The below returns an error
Get-Organization -Name <somename> | Get-Department
As you can see, the return type OrgModel has a property defined called OrgName which should automatically bind to Get-Department parameter OrgName but it is not and giving the below error:
C:\WINDOWS\system32> Get-Organization -Name contoso | Get-Department
Get-Department : The input object cannot be bound to any parameters for the command either because the command does not take pipeline input or the input and its properties do not match any of the parameters that take pipeline input.
At line:1 char:44
+ ... et-Organization -Name contoso | Get-Department

Any idea ?

Answer 1

Using the command that #PeterSerAl mentioned I noticed the return time was incorrectly set to a collection.
It works after fixing it.
Thanks
