Stripe gateway not generating Stripe token

[GarPit]

As a result, we'll get Sending credit card numbers directly to the Stripe API is generally unsafe.

So, the problem in JS.

We have this:

Spree.stripePaymentMethod = $('#payment_method_' + 3);

And later:

if Spree.stripePaymentMethod.is(':visible')

And last one returns false in Chrome console, when this payment method is actually visible and $('payment_method_3').is(':visible') returns true.

This is well-known jQuery problem/feature of selectors snapshots - https://stackoverflow.com/questions/11868899/how-can-i-refresh-a-stored-and-snapshotted-jquery-selector-variable

Maybe to store in Spree.stripePaymentMethod just a selector string, not a snapshot?
