Expand description

External error code – used for client responses

Design principles: Stability: Error codes should not be modified arbitrarily once they have been defined, in order to ensure compatibility with clients. 2. Simplification: Only the necessary error information is displayed, without any details about the internal implementation. 3. Standardization: Adherence to common error code design specifications such as those for HTTP/GraphQL
