No, it wasn't the "world's least helpful error message"

Last wee, I commented about a problem with AngularJS and an error message that I found incredibly unhelpful.  Turns out it was more helpful than I knew although there are still problems.

Here's what it looked like in Chrome DevTools:

But that's a live link, so all you have to do is click on it and you're redirected to an AngularJS page that (hopefully) provides more information. Here's the link, and here's the link text iteself: quite a mouth/link full:

What you get when you click on this link is a customized error page -- pretty neat way to handle things and sometimes it works very well -- this example was spot on:

But here's one that wasn't nearly so helpful:

So...much better than I thought, although there are still some head-scratchers.
