.NET8迁移后Amazon S3流上传报错：内容超出Content-Length

将项目从.NET6迁移至.NET8并更新所有包至最新版本后，向Amazon S3存储上传流时持续抛出错误：
System.Net.Http.HttpRequestException: Unable to write content to request stream; content would exceed Content-Length

其中STP.BlobStorage是无法获取源码的第三方包，上传请求由AmazonS3Client内部发起。

上传代码实现 #

public async Task UploadAsync(Stream sourceStream, string fullPath, string contentType, CancellationToken cancellationToken = default(CancellationToken))
{
    Guard.ValidateFullPath(fullPath, "fullPath");
    try
    {
        TransferUtility transferUtility = new TransferUtility(_s3Client);
        await transferUtility.UploadAsync(sourceStream, _bucketName, fullPath, cancellationToken);
        _logger.LogDebug("Uploaded stream to {fullPath}", fullPath);
    }
    catch (AmazonServiceException ex3)
    {
        AmazonServiceException ex2 = ex3;
        _logger.LogError(ex2, "Got AmazonServiceException in UploadAsync while uploading object to '{fullPath}'.", fullPath);
        throw new StorageProviderException($"Got AmazonServiceException in {"UploadAsync"} while uploading object to '{fullPath}'.", ex2);
    }
    catch (Exception ex4)
    {
        Exception ex = ex4;
        _logger.LogError(ex, "Got exception in UploadAsync while uploading object to '{fullPath}'.", fullPath);
        throw new StorageException($"Got exception in {"UploadAsync"} while uploading object to '{fullPath}'.", ex);
    }
}

无法在请求发起时直接控制Content-Length参数，请问此次从.NET6到.NET8的迁移为何会引发该问题？
