Stripe.js 2 error when converting a card into token

Greetings
Im implementing stripe payments using Stripe.js 2 plugin but i keep reciving the following error when converting a card into StripeToken.

“The plugin Stripe.js 2 / action Convert card into a Stripe Token threw the following error: ReferenceError: Stripe is not defined
at eval (PLUGIN_1491714407143x279212378954661900/Stripe-js-2-element_action–Stripe-Token-Convert-card-into-.js:43:5)

This is the link for the preview of tha app: https://poolride.bubbleapps.io/version-test/test_cc?debug_mode=true

Does anyone have run in to that problem?

PS: i created a brand new app to test if i get the same error and it seems to be working just right
