code property

A short, stable machine-readable code identifying the kind of problem. Safe to switch on. One of: 'missing_required', 'type_mismatch', 'null_not_allowed', 'invalid_enum', 'invalid_enum_index', 'key_type_mismatch', 'invalid_uri', 'invalid_bigint', 'invalid_base64', 'min_length', 'max_length', 'regex_mismatch', 'invalid_email', 'invalid_url', 'invalid_uuid', 'min_value', 'max_value', 'must_be_past', 'must_be_future', 'custom_validation_failed' or 'unknown_union_type'. See the "Issue codes" section of the README for what each one means.
