Class: DefaultFailureConverter

common.DefaultFailureConverter

Default, cross-language-compatible Failure converter.

By default, it will leave error messages and stack traces as plain text. In order to encrypt them, set encodeCommonAttributes to true in the constructor options and use a PayloadCodec that can encrypt / decrypt Payloads in your WorkerOptions.dataConverter | Worker and ClientOptions.dataConverter | Client options.
