【报Bug】视频转码api报错 extStorageManager.pfop is not a function

示例代码：

async transcodeVideoMp4 (data) {  
        let {  
            cloudPath, // 前端传过来的文件路径  
        } = data;  
        const extStorageManager = uniCloud.getExtStorageManager({  
            provider: "qiniu",  
            domain: "cdn.mannanedu.top", // 域名地址  
        });  
        const urlsafeBase64Encode = (text) => {  
            let encoded = Buffer.from(text).toString('base64');  
            return encoded.replace(/\//g, '_').replace(/\+/g, '-');  
        };  
        let saveas = urlsafeBase64Encode("dc-qiniu-aliyun-mp-a071697e-6402-4c6a-9d2a-79196812197e-eaf");  
        let fops = `avthumb/mp4/vcodec/libx264/acodec/libmp3lame|saveas/${saveas}`;  

        console.log('cloudPath', cloudPath)  
        console.log('extStorageManager', cloudPath)  
        await extStorageManager.pfop({  
            cloudPath: cloudPath,  
            fops,  
            notifyURL: "https://domain.com/ext-storage-transcode-notice"  
        });   
}
