@fpdrozd I think there's something wrong with the Test & Lint / Test api-client and composables (pull_request) step. It fails when building the api-client. Could you take a look?

@rafalcymerys This is probably related to the axios upgrade in storefront (vuestorefront/vue-storefront#6848). I've added explicit response typing for the getPaymentConfirmationData and getPaymentMethods api calls. Should work now.

Btw, what is that intents spree api endpoint? (/api/v2/storefront/intents/payment_confirmation_data). Couldn't find it in the docs. Is it some custom Stripe integration?

[rafalcymerys]

It's core Spree, but it could be missing from the docs. Let's take a look at it and make sure it's in swagger.
