AWS Translate 代码引发无法解组错误

Question

我正在尝试使用 AWS-translate 翻译 s3 存储桶中的 mp3 文件。目前，我抛出了以下错误。我的代码是：

public class ProviderTranscribeController {

private static final Logger LOGGER = Logger.getLogger(ProviderTranscribeController.class);

private AmazonTranscribe client = AmazonTranscribeClient.builder().withRegion(Regions.EU_WEST_2).build();
final AmazonS3 s3 = AmazonS3ClientBuilder.standard().withRegion(Regions.EU_WEST_2).build();


public TranscriptionJob transcribeMp3(){
    StartTranscriptionJobRequest request = new StartTranscriptionJobRequest();
    request.withLanguageCode(LanguageCode.EsUS);
    Media media = new Media();

    media.setMediaFileUri(Uri);

    request.withMedia(media).withMediaSampleRateHertz(8000);
    String transcriptionJobName = "myJob";
    request.setTranscriptionJobName(transcriptionJobName);
    request.withMediaFormat("mp3");
    LOGGER.info(request.getLanguageCode());
    LOGGER.info(request.getMedia().getMediaFileUri());
    LOGGER.info(request.getMediaFormat());
    LOGGER.info(request.getMediaSampleRateHertz());
    LOGGER.info(request.getTranscriptionJobName());

    client.startTranscriptionJob(request);

    GetTranscriptionJobRequest jobRequest = new GetTranscriptionJobRequest();
    jobRequest.setTranscriptionJobName(transcriptionJobName);
    TranscriptionJob transcriptionJob;
    transcriptionJob = client.getTranscriptionJob(jobRequest).getTranscriptionJob();

    return transcriptionJob;
}
}

我得到的错误是：

在 Boris 的想法的帮助下，我发现我正在为 s3 和转录使用不同的版本。
