Errors

Every Network error carries a stable numeric error_code and a machine-readable reason. This page lists the logical (domain) error codes Network can return. For the full error envelope (the google.rpc.Status shape, the reason and metadata fields, and how codes are structured) see Errors.

Network codes begin with 5 (for example 5300001, read as 5_300_001: service, group, specific error). The wire value is always the flat integer; you can match on either error_code or reason, both are stable.

The Status column is the canonical gRPC status the error maps to, which the gateway renders as the matching HTTP status (see the status codes table).
