Creating custom Project properties script

[KrisTheCrazie]

Hello,

I am trying to automate the project creation, and creating a number associated to every project. This script is being used in the Project under Custom Properties. Currently I have this code setup to format it in the way required. However when running it, I get a conversion error:
Conversion error : key:PRJDetails.Number,value:003,encrypted:false - class java.lang.String Not a properties

Script presenting the error:

function Handler($context, $inputs) 
{    
    # Customizing the project number to have 3 digits
    Write-Host "Formating project number"
    $prjnum = $inputs.projectnumber
    $custnum = $prjnum | % padleft 3 '0'
    Write-Host "Project Number is $prjnum"
    Write-Host "Formated Number is $custnum"

    # Formating number for the customproperties variable
    Write-Host "Now Formating for Project Variable"
    $customProperties = 
    "key:PRJDetails.Number,value:$custnum,encrypted:false"
    Write-host "Formated Variable is : $customProperties"
    function ToArray
    {
        begin
        {
            $output =@();
        }
        process
        {
            $output += $_;
        }
        end
        {
            return ,$output;
        }
    }
    $array = $customProperties | ToArray
        Write-host "Converted to Array : $array"
    $output=@{customProperties = $array}
    return $output
}

You might need to format the custom properties as an array of strings.

function Handler($context, $inputs) 
{    
    # Customizing the project number to have 3 digits
    Write-Host "Formatting project number"
    $prjnum = $inputs.projectnumber
    $custnum = $prjnum.PadLeft(3, '0')
    Write-Host "Project Number is $prjnum"
    Write-Host "Formatted Number is $custnum"

    # Formating number for the customproperties variable
    Write-Host "Now Formatting for Project Variable"
    $customProperties = @(
        "key=PRJDetails.Number,value=$custnum,encrypted=false"
    )
    Write-Host "Formatted Variable is : $customProperties"

    $output = @{
        customProperties = $customProperties
    }
    return $output
}

Thanks for that, it still gives the same error unfortunately.
