Description

At this moment error handling is managed manually with a try/catch on each API request, which is a problem if we want to manage behaviours in the same way for any error that is been thrown.

This PR unifies error management in a useErrorHandler hook so all errors in API requests should be managed by this hook.

The PR introduces the SilentError class too, for cases where we need to stop the execution but do nothing and log a warning, like when a onBefore function implemented by the user returns false.
