未触发uploadProgress rn-fetch-blob

Question

在开发react原生应用程序时，我在两个平台(iOS和安卓)上都遇到了以下问题

环境：

"react-native": "^0.61.1",
"rn-fetch-blob": "^0.12.0"

我正在做一个将视频上传到服务器的多部分请求。鉴于此请求需要时间，我想向用户显示进度。

根据库文档，有一个uploadProgress回调：https://github.com/joltup/rn-fetch-blob#uploaddownload-progress，但在我这端不起作用。

下面是我的代码：

RNFetchBlob.fetch(
    'POST',
    `${REACT_APP_API_DOMAIN}/upload/video`,
    {
      Authorization: `Bearer ${token}`,
      timestamp: `${timestamp}`,
      'Content-Type': 'multipart/form-data',
    },
    [
      {
        name: 'video',
        filename: `video.${file.split('.')[file.split('.').length - 1]}`,
        data: RNFetchBlob.wrap(file),
      },
    ],
  )
    .then(() => {
      Notifier.showNotification({
        title: 'The videos was successfully saved!',
        description: "We're processing it, your profile will be updated soon!",
        Component: NotifierComponents.Alert,
      });
      setStatus(statusEnum.PROCESSING);
      completeCallback();
    })
    .uploadProgress((written, total) => {
      console.log('uploaded', written / total);
    })
    .catch(err => {
      Notifier.showNotification({
        title: 'There was an error uploading the video',
        description: err.toString(),
        Component: NotifierComponents.Alert,
        componentProps: {
          alertType: 'error',
        },
      });
      setStatus(statusEnum.FAILED);
      completeCallback();
    });

有什么想法吗？

这个问题已经在这里得到了回答：https://github.com/joltup/rn-fetch-blob/issues/670#issuecomment-696016355

基本上，我必须交换then和uploadProgress回调。
