Error Codes

Error codes returned by the cloud agent

The cloud agent returns informative errors codes where possible, resorting to a generic message for all other cases.

Error codes

Code	Description
InvalidArgumentError	Returned by any query or mutation when invalid arguments or invalid argument combinations are submitted.
DecodingError	Returned when a string-encoded JSON input argument cannot be successfully decoded to valid JSON.
ResourceAlreadyExistsError	Returned when attempting to create a resource (e.g. an AnoncredsSchema etc.) which already exists.
LedgerWriteError	Returned when the cloud agent fails to write an AnoncredsSchema or AnoncredsCredDef to the ledger, and the cause of failure is unknown.
ResourceNotFoundError	Returned when attempting to fetch a resource (e.g. a Connection, Credential, exchange, ledger resource etc.) which does not exist.
CannotIssueWithCredDefError	Returned when attempting to issue an Anoncreds credential but the specified credDefId references a credential definition which was not created by the cloud agent.
ExchangeInAbandonedStateError	Returned when attempting to perform an operation on an exchange, but the exchange is in the state ABANDONED and therefore the cloud agent cannot fulfill the operation request.
IncompletePresentationError	Returned when attempting to accept a proof request by submitting a presentation, but the submitted presentation is lacking sufficient arguments such that the proof request is not fulfilled. e.g. missing referents

Generic errors

As a fallback, generic errors are returned from the cloud agent in the following form, where <uuidv4> is replaced with a random UUID v4.
