I’m trying to send audio OGG file bytes via feign client in java to the API endpoint, but I’ve got an 400 bad request → “error_message” : “OGG header has not been found”. But if file was sending from postman (with same headers and OGG file) everything works just fine.

FeignClient:

@FeignClient(name = "${integration[0].speech.name}",
        url = "${integration[0].speech.url}",
        configuration = SpeechRecognizerConfig.class)
public interface YandexSpeechRecognizerClient {

    @PostMapping
    @Headers({
            "Content-Type", "audio/ogg"
    })
    RecognizedTextResponse recognizeText(@RequestHeader("Authorization") String token,
                                               @RequestParam("lang") String lang,
                                               @RequestBody ByteArrayResource oggFileBytes);

Feign client config:

@Bean
    public Logger.Level feignLoggerLevel() {
        return Logger.Level.FULL;
    }

    @Bean
    public Client httpFeignClient() {
        return new OkHttpClient(new okhttp3.OkHttpClient.Builder()
                .build());
    }

@Bean
    public Feign.Builder speechFeignBuilder(@Autowired Logger.Level logLevel, @Autowired Client client) {
        return Feign.builder()
                .logger(new Slf4jLogger(log))
                .logLevel(logLevel)
                .client(client);
    }

Test method:

byte[] bytes = Files.readAllBytes(oggFile.toPath());
RecognizedTextResponse yandexRecognizedTextResponse = underTest.recognizeText(
                "Bearer " + authClient.getToken().getAccessToken(),
                "en-EN",
                false,
                false,
                "123123123",
                new ByteArrayResource(bytes)
        );

Already tried gagravarr vorbis, injection with @Value, MultipartFile. Nothing works
