我当时正在试用firebase，我写了一段代码来试用云存储服务，但是我意识到如果我在启动后400 - 500 ms之后暂停文件上传，它会抛出一个未知的错误。

async function uploadFile() {
    //file comes from a file a file input html element
    const uploadTask = uploadBytesResumable(ref(cloudStorage, `videos/${file.name}`),file);

    uploadTask.on("state_changed",(snapshot) => {
        const uploadProgress = (snapshot.bytesTransferred / snapshot.totalBytes) * 100;
            
        //I update a state
        setProgress(Math.floor(uploadPercent));

    switch (snapshot.state) {
    case "paused":
        console.log("Upload paused");
    break;
    case "running":
        console.log("Upload resumed");
    break;
    }
},
(e) => {
    console.log("an error occurred...", e.serverResponse, e);
 },
() => {
    console.log("upload completed!");
     });

    setTimeout(() => {
    uploadTask.pause();
    }, 400); 
     //result => download is paused with no error

    setTimeout(() => {
    uploadTask.pause();
    }, 500); 
    //result => unknown error occurred

}

上传工作正常错误来时，我试图暂停操作，我会很感激，如果有人能告诉我一条出路...
