Version: io.minio:minio:8.5.15

Common logic:
`minioClient = MinioClient.builder().endpoint(minioUrl, minioPort, false).credentials(accessKey, accessSecret).build();

if (!minioClient.bucketExists(BucketExistsArgs.builder().bucket(MINIO_BUCKET).build())) {
minioClient.makeBucket(MakeBucketArgs.builder().bucket(MINIO_BUCKET).build());
}
`

Working code:
InputStream targetStream = new ByteArrayInputStream(content.getBytes()); minioClient.putObject(PutObjectArgs.builder().bucket(MINIO_BUCKET).object(filename).stream(targetStream, content.getBytes().length, -1).build());

Failing code:
InputStream targetStream = new ByteArrayInputStream(content.getBytes()); minioClient.putObject(PutObjectArgs.builder().bucket(MINIO_BUCKET).object(filename).stream(targetStream, content.getBytes().length, -1).contentType("json").build());

Would like to understand why "contentType("json")" causes the SignatureDoesNotMatch error.
