我试图通过Box Java SDK将一个新版本的文件上传到Box。上传后，我得到了这个异常。

但我注意到该文件已成功上传为新版本。这是API的问题吗？
我使用过的代码片段：-
byte[] bytes = multipartFile.getBytes();
inputStream = new ByteArrayInputStream(bytes);
boxFile = new BoxFile(api, fileId);
boxFile.uploadVersion(inputStream);
我不明白为什么会发生这种情况。但即使在出现这种异常之后，我的文件上传也能正常工作。所以我们可以忽略这一点，继续上传。
