Describe the Bug/Issue
I use the "/" to turn my cooldowns on and off before a boss fight. When I press "/" I get the following error
"Message: Interface\AddOns\Hekili\Options.lua:9386: attempt to call field 'ScanEvents' (a nil value)

I tried right-clicking my datatext bar where Hekili is located to open the dialog box, then I select toggles on the left and go to the box associated with "cooldowns" and check the box to turn it on or off. I get another error message below:

When I open the "Issues reporting" tab I immediately get the following in my error window

Expected behavior
What I expect to happen is my cooldowns option during my rotation to appear in the rotations. They do see to appear as they are supposed to but not without having to clear the error message which often times I find myself doing during a boss fight, which is when I turn my cooldowns on for my rotation.

NOTE: In all of my copy and paste of the error messages, I add quotation marks at the beginning and end of each message even if there already was a quotation mark present from the message itself there. I know it may seem obvious, but just clarify to be as thorough and clear as possible.

I use ElvUI as my main UI interface. It does not seem to matter which character I am on to produce the error. I tried it on a Ret and Prot pally, and a Holy priest over the last few days.

The only reason this would happen is if you have something pretending to be WeakAuras without WeakAuras installed or up and running.

I'm putting in some babyproofing for this that I shouldn't have to do. Closing this ticket.
