I'm using Laravel 5.8 and Sweetalert v2 and I'm trying to trigger this alert on Blade with it:

Swal.fire({ title: '
Updating user status
', html: '
Wait...
', width: 400, padding: '1em', background: '#fff url(/images/cream_pixels.png)', timer: 1000, onBeforeOpen: () => { Swal.showLoading() }, });

It pops up correctly but doesn't show the loader and shows me this error on the console:

SweetAlert2: Unknown parameter "onBeforeOpen"

So what’s the problem here?
