New-UDGridLayout is confusing

I am having a difficult time understanding what exactly I am suppose to wrap in the “New-UDGridLayout -Content {}” script block. I constantly find myself battling the following error message: There was an error rendering component of type ud-grid-layout. TypeError: t.children.map is not a function. The documentation explains how to use this option fairly well, but it isn’t exactly clear on what needs to go inside this script block and what can be excluded. I’ve tried wrapping some of my dashboards in this scriptblock and sometimes it works, but often it complains so I try to minimize what is inside. Any help on how to troubleshoot this would be nice! (P.s. I am using the latest version of PSU)
