KB Engine Notification Loop: Safari JavaScript error

I built a macro to open safari and get a URL to brain.fm. Instantly, KB starts adding hordes of error messages in the notification center. I restart KB. I restart Safari. But nothing works except a reboot.

This is what I get:


This is what the rule looks like:

Running KB version 8.2.3

The URL opens just fine. But the error messages won't stop.

Thoughts and suggestions? Thank you in advance.

Have you done exactly what the KM Log message is telling you to do?


I would, but I'm clearly missing where that is, exactly. I've gone through Safari's menus and don't see a Develop menu.

If you don’t see the Develop menu in the menu bar, choose Safari > Preferences, click Advanced, then select “Show Develop menu in menu bar.”


Just for good measure, here's a screenshot to point out where exactly in Safari's preferences to find this, since it can be easy to overlook:
