Perhaps the issue is that the column isn't loading the image, so the selectedRow won't work until that happens.
So where {{ item }} exists, what would I be putting here to pull the image URL given the previous reply? Should be dot notation of logo.url as far as I can tell.
As I dig it's as if the logo object can't be used.
It's rather unclear to me how this magically works given the displayed error. With that said, at least it works. What I likely overlooked is I already had the "source" selected which means I didn't need the full dot notation in the mapped value.
All I needed was something more simple than met the eye.
