二、HANDLING DISMISSALS

When an alert is dismissed by the user, the Promise returned by swal() will reject with a string documenting the reason it was dismissed:

String	Description	Related configuration
'overlay'	The user clicked the overlay.	allowOutsideClick
'cancel'	The user clicked the cancel button.	showCancelButton
'close'	The user clicked the close button.	showCloseButton
'esc'	The user clicked the Esc key.	allowEscapeKey
'timer'	The timer ran out, and the alert closed automatically.	timer

If rejections are not handled, it will be logged as an error. To avoid this, add a rejection handler to the Promise.
Alternatively, you can use .catch(swal.noop) as a quick way to simply suppress the errors:

swal(...)
  .catch(swal.noop)
