Exceptions / Errors

AuthException
DVAIProviderException

DVCompensationException
Thrown when a compensation handler itself fails during rollback.
DVFileStorageException
Thrown when an object store rejects a request.
DVMailProviderException
Thrown when a mail provider rejects a message. Delivery failures are never swallowed - a caller always learns the message did not go out.
DVOAuth2Exception
DVPushProviderException
Thrown when a push service rejects a notification.
DVSearchProviderException
Thrown when a hosted search service rejects a query or answers with a shape Dartvel cannot read. A failed search never degrades to an empty page.
DVSecretNotFoundException
Thrown when a secret is asked for and no source provides it.
DVSmtpException
Thrown when the server answers with an unexpected status.
DVUnknownModuleException
Thrown when a module is requested that was never registered.
