Hi there. I have a question about clean architecture. Which module (data, domain, presentation) is responsible for handling API errors, for example if I have API method /login and it returns error Email is incorrect where should I handle it? I guess in repository inside data module/layer, but maybe I missed smth.

I use to do that handling on domain layer. It make sense for me because it is near to the presentation layer, and presentation will only comsume those exceptions coming from domain and show it for the user in someway.

(I'm not sure if my thoughts are correct. 😄 Just sharing my option)

Anyway, I'm curious about other point of view 🙂

Domain layer I believe

I would do it in domain layer too.
IMHO, data should be responsible to serve raw data, and the domain layer should handle it accordingly to the domain rules, given by the person responsible for it i your org (Product Owner, business, etc etc)

Thank you guys for your answers. Will handle it in domain, agree with @nounours

Hm, I'd say in data and optionally in domain, no? You don't want api exeptions in domain because that's dependency leak. You handle it once in data, map it to some sort of error model from domain. Then, in domain itself you can do something with it, or just pass it to ui and ui will map it to its own models.
