Error Handling with Stripe

We’re using the action ‘Collect the User’s CC Information’ from the ‘Stripe’ plugin. When the credit card number is invalid, we get this annoying pop-up message, when we’d rather use the AirAlert plugin when we get an error. We’ve tried using the ‘when an unhandled error occurs’ to do this, but it doesn’t seem to catch the error. Any ideas on how to disable the built-in browser popup?
