ConvertTo-Yaml - PSCustomObject with $null properties

[thecliguy]

Steps to reproduce

$CustomObject = [pscustomobject]@{firstname="John"; url=$null; comment="foo bar"}
ConvertTo-Yaml $CustomObject

Outcome

Convert-PSObjectToGenericObject : Cannot bind argument to parameter 'Data' because it is null.

Workaround

I'm currently using a modified version of Convert-PSCustomObjectToDictionary to accommodate members with a value of $null:

function Convert-PSCustomObjectToDictionary {
    Param(
        [Parameter(Mandatory=$true,ValueFromPipeline=$true)]
        [PSCustomObject]$Data
    )
    $ret = [System.Collections.Generic.Dictionary[string,object]](New-Object 'System.Collections.Generic.Dictionary[string,object]')
    foreach ($i in $Data.psobject.properties) {
		If ($i.Value) {
			$ret[$i.Name] = Convert-PSObjectToGenericObject $i.Value
		}
		Else {
			$ret[$i.Name] = ""
		}
    }
    return $ret
}
