Context

Iberia proposes the inclusion of new error messages in the error detailing flow, following the established processes in stories:

The objective is to enhance error communication between the backend and frontend.

image-20241009-123944.png

✅ Proposed Solution

To address these issues, we propose the creation of new error classes in the backend that will be sent to the frontend. This implementation will include specific error codes for different scenarios, such as payment cancellations, instead of using generic codes. This change will allow the frontend to display more informative and contextualized error messages, improving clarity and the overall user experience.

Backend

After the solution approval, will need to update the below documents with new classes, code errors, and any important things.

(error) Out-of-scope

It is out of the scope to create the Lokalise key, since the key can be added directly to the Lokalise portal.

For help, there is a list of keys that can be created in the Lokalise portal in the description error table (Lokalise key column).
