I want to set extra options in error response. Didn't find the exact solution anywhere. tried passing in the body ``` const errors = require('restify-errors'); new errors.MethodNotAllowedError({ body: { extra: option } }, some-error-message)); ``` what's the exact method to allow some extra options in error response? Is there a way to set the default for all the errors and just pass the extra field parameters? Also, I just want options in already existing error methods.
