Does this manifest only for json_serializer or for other parameters too?

[beerline]

@StarProxima i can confirm same error for unknown_enum_value parameter.

I looked through source files and i found that at swagger_parser-1.17.3/lib/src/config/swp_config.dart:279 getting default config overrides only outputDirectory. So if no parameter was defined under schema it would take default value, which is for json_serializer is JsonSerializer.jsonSerializable.
