Sandbox testing cards checkout always fail

Hi,

I am trying to run a manual integration test of 4Geeks payments workflow using the Sandbox features to evaluate if this service is a good option to adopt on my e-commerce projects for Costa Rican clients.

When I get to the Checkout Payment screen provided by the /payments endpoint and use any of the testing cards from the official docs for a test payment I always get and error response back that somenthing went wrong. I already filled all the required fields and used a positive integer on the CVC.

I would like to know if this is supposed to work successfully with the cards on the documentation or is the expected behaviour of the sandbox? I also see some information not properly showing on the checkout UI so Im not sure if this is acutally something wrong or to be expected because of being the Sandbox?

I would like to test an actual simulation of a payment to evaluate the console functionality and the overall UI/UX from the payment checkout workflow that my clients would experience if I decide to integrate this service into their e-commerce.

Thanks.
