其他相关日志：
通过打印 上传文件时progressCallback 回调信息中可以得知：
data大小会比实际文件大小要大，不知道是什么原因导致的。
报错unexpected file size 的好像都会有这个问题

Start with the ResumeUploader entry point and its progressCallback handling. Reproduce the 84MB upload and compare the reported data size with the actual file size, then inspect the request sent to the mkfile endpoint. Done means the upload completes without an "unexpected file size" response and progress data matches the file size.
