Here's an error in some code I'm currently developing;
The primary problem here is that there is no line number, so it makes it very hard to pinpoint the issue. It also doesn't give you the snippet of code that triggered the exception, like you'd normally expect to see.
We upgraded to v12 back in November last year, and before that I could have sworn the Exceptions for JavaScript-based automations were more useful than they are now.
Is this something other people have noticed too?
