Hey @adam,

We are running a dashboard with a custom PS module with a parameter for Environment. When we try to run the commands inside the dashboard, we are receiving the following error:

Cannot validate argument on parameter 'Environment'. Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')

We are using an IValidateSetValuesGenerator class to dynamically get [ValidateSet] values.

using namespace System.Management.Automation

class Environment : IValidateSetValuesGenerator {
    [string[]] GetValidValues() {
        $Configuration = Get-Content -Path (Join-Path -Path $PSScriptRoot -ChildPath 'Configuration.json') |ConvertFrom-Json
        $Values = foreach ($Environment in $Configuration.Environment.PSObject.Properties.Name) {
            $Environment
        }
        return $Values
    }
}

Thanks!
