Creating new methods to validate the new errors is good because it will allow the validation of specific attributes (for example: err.extensions?.rbiErrorDomain) without needing to use the feature flag or the optional creation.
How?
The new interface IRbiError and new methods will be parseGraphQLRBIError and parseGraphQLRBIError:

In addition of creating the new methods mapRBIErrors and parseGraphQLRBIError, it will need to create the other methods:
