使用webupload使用分片上传问题

我上传文件不大，不分片上传的时候没有毛病
代码设置如下：

@AdaptBy(type = UploadAdaptor.class, args = {"ioc:imageUpload"})
    @POST
    @At(value = {"/open/upload/?/?/image"},top = true)
    @Ok("json")
    public Object images(String type,String name,@Param("image") TempFile[] files,@Param("")NutMap data, HttpServletRequest req, AdaptorErrorContext err) {
        try {
            if (err != null && err.getAdaptorErr() != null) {
                return Result.error("文件不合法:" + err.toString());
            } else {

当分片传输的时候，这里的err不为空，导致所有数据为null，同时报错如下：

[DEBUG] 2018-07-06 15:46:20,050 org.nutz.mvc.upload.FastUploading.parse(FastUploading.java:133) - Upload File info: FilePath=[test.mp4],fieldName=[image]

不清楚是哪儿不对，请指教！
