The provided 'x-amz-content-sha256' header does not match what was computed.

I have two rather similar methods:

`
public async Task UploadAsync(IFormFile file, long? documentTypeId, bool modifyName = true)
{

    var customFileName = (modifyName ? (DateTime.UtcNow.ToString("yyyyMMddHHmmss") + "_") : string.Empty) + file.FileName;

    // Make a bucket on the server, if not already present.
    var beArgs = new BucketExistsArgs()
        .WithBucket(_bucket);

    bool found = await _minioClient.BucketExistsAsync(beArgs).ConfigureAwait(false);
    if (!found)
    {
        var mbArgs = new MakeBucketArgs()
            .WithBucket(_bucket);

        await _minioClient.MakeBucketAsync(mbArgs).ConfigureAwait(false);
    }

    // Upload a file to bucket.
    var putObjectArgs = new PutObjectArgs()
        .WithBucket(_bucket)
        .WithObject(customFileName)
        .WithStreamData(file.OpenReadStream())
        .WithContentType(file.ContentType)
        .WithObjectSize(file.Length);

    await _minioClient.PutObjectAsync(putObjectArgs).ConfigureAwait(false);

    var createDocument = new CreateDocument()
    {
        DocumentTypeId = documentTypeId,
        Link = customFileName,
        Name = file.FileName,
    };

    var documentId = await _documentRepository.CreateAsync(_mapper.Map<ICreateDocumentDmo>(createDocument))
        ?? throw new EppsException(TextMessages.FileUploadError);

    return (await _documentRepository.GetAsync(documentId)) !;
}`

Which works. And second one, which throws an exception "MinIO API responded with message=The provided 'x-amz-content-sha256' header does not match what was computed."

`public async Task UploadAsync(byte[] data, string fileName, string contentType, bool modifyName = true)
{
var customFileName = (modifyName ? (DateTime.UtcNow.ToString("yyyyMMddHHmmss") + "_") : string.Empty) + fileName;

    // Make a bucket on the server, if not already present.
    var beArgs = new BucketExistsArgs()
        .WithBucket(_bucket);

    bool found = await _minioClient.BucketExistsAsync(beArgs).ConfigureAwait(false);
    if (!found)
    {
        var mbArgs = new MakeBucketArgs()
            .WithBucket(_bucket);

        await _minioClient.MakeBucketAsync(mbArgs).ConfigureAwait(false);
    }

    // Upload a file to bucket.
    using (var streamData = new MemoryStream(data))
    {
        var putObjectArgs = new PutObjectArgs()
            .WithBucket(_bucket)
            .WithObject(customFileName)
            .WithStreamData(streamData)
            .WithContentType(contentType)
            .WithObjectSize(data.Length);

        await _minioClient.PutObjectAsync(putObjectArgs).ConfigureAwait(false);
    }

    var createDocument = new CreateDocument()
    {
        Link = customFileName,
        Name = fileName,
    };

    var documentId = await _documentRepository.CreateAsync(_mapper.Map<ICreateDocumentDmo>(createDocument))
                     ?? throw new EppsException(TextMessages.FileUploadError);

    return (await _documentRepository.GetAsync(documentId)) !;
}`

I tried using memory stream, I tried setting Content-Type by hand but nothing works. I am so lost. Does anybody know what is wrong here?
