It is because you haven't connected your Stripe Payment widget to your Stripe account.

Please check the link below on how to setup your Stripe Payment Integration.

Since your Stripe settings is on Test Mode, make sure you also enabled Test Mode on your Stripe Dashboard.

Please see this thread about "Test" and "Live Mode" from stripe https://stripe.com/docs/dashboard#livemode-and-testing
