Toast Notifications not Working

@vlad I have ben using the AirDev AirAlert plugin for quite some time and I love it!
But then recently I started getting this error? What’s weird is that it still works perfect on my other apps.
(for reference, All that is going on here is a button that should trigger an Alert)
Any idea what is going on?

That would happen if your browser isn’t loading the file (try clearing cache & doing a hard refresh)

@gaurav If you could look into the error would be a great help.
