问腾讯云短视频上传失败错误码1004：upload file does not exist ？

上传一部分之后，显示找不到文件，请问这是为什么。

代码如下

plug.uploadVideo({

"videoPath": that.m_videoPathTemp.replace('file://', ''),

"fileName": that.mTeacherInfo.FTeacherName,

"signature": json.Data, //签名信息

"coverPath": that.mTeacherInfo.FTeacherHeadImg

}, ret => {

console.log(ret)

if (ret.code == 7 && ret.playUrl) {

that.m_videoPath = ret.playUrl;

that.FFileID = ret.fileId,

that.RealSave();

}

});

----------返回的错误信息如下：-------------------------------------------------

{

"msg": "视频上传出错",

"code": "6",

"errCode": 1004,

"errMsg": "cos upload error:com.tencent.cos.xml.exception.CosXmlClientException: upload file does not exist"

}
