Hi, I’m trying to retrieve the Current Account using a Nanoflow that is called on a Native Page. It’s a simple Retrieve action, First only, with [id = '[%CurrentUser%]'] in the XPath constraint. When I run this Nanoflow on a Webpage, it runs as expected. However, when I run it on a Native Page, the debugger crashes (see Stack Trace below). Any idea what is causing this? Thanks, Cris System.FormatException: String was not recognized as a valid Boolean.
