Endpoint Conversion Exception

PowerShell Universal
1 
Product: PowerShell Universal
Version: 1.5.14

Hi @adam

I created a dashboard and an endpoint in PowerShell Universal like so:

$ProcessName = "svchost"

New-UDDashboard -Title "Hello, World!" -Content {

    New-UDTypography -Text $Cache:Hello

}

$Schedule = New-UDEndpointSchedule -Every 10 -Second

New-UDEndpoint -Schedule $Schedule -Endpoint {

    $Processes = Get-Process -Name $ArgumentList[0]

    $Cache:Hello = $Processes.Name -join ','

} -ArgumentList $ProcessName

Everything works fine but if I take a look in the Log Section of that particular dashboard I se the following error:

Are you aware of that. Just want to let you know.

Iā€™m getting the same exception.

What happens if you pipe the New-UDEndpoint call to Out-Null?

New-UDEndpoint -Schedule $Schedule -Endpoint {

    $Processes = Get-Process -Name $ArgumentList[0]

    $Cache:Hello = $Processes.Name -join ','

} -ArgumentList $ProcessName | Out-Null

Hi @adam,

if I write

$null = New-UDEndpoint -Schedule $Schedule -Endpoint {

    $Processes = Get-Process -Name $ArgumentList[0]

    $Cache:Hello = $Processes.Name -join ','

} -ArgumentList $ProcessName

That brings me no error and also the dashboard works as expected.

Thank you for helping.
