How to access string indexer on a collection in Powershell

You can get following error trying to access the property (aka hashtable)

Unable to index into an object of type System.Management.Automation.PSParameterizedProperty

Resolution:

You need to place curly braces around the hyphenated property name. This should work:

$item.{some-property}
