Reactjs 无法打开文件，共享后，响应本机

我已经使用react native share创建了一个共享函数，该函数获取api，以便共享一些图像，但是当我尝试通过whatsapp共享时，它会抛出一个错误：无法打开文件

我的共享功能：

shareImage= (item) => {
   console.log('hello',item)
  RNFetchBlob.fetch('GET', `some url`)
    .then(resp => {
      console.log('response : ', typeof resp);
      console.log('fff', JSON.parse(resp.data));
      let ab = JSON.parse(resp.data);
      console.log('data', ab)
      let base64image = ab;
      share('data:image/jpeg;base64,' + base64image);
    })
    .catch(err => {
      err && console.log(err);
    });

  share = base64image => {
    console.log('base64image : ', base64image);
    var shareOptions = {
      title:item.title,
      url: base64image,
      // message: 'https://somelink.com some message',
      subject: 'Subject'
    };

    Share.open(shareOptions)
      .then(res => {
        console.log(res);
      })
      .catch(err => {
        err && console.log(err);
      });
    }
  };

共享时我的日志：

请告诉我哪里出了问题，已经两天了，我仍然卡在那里，请帮助。

您添加了权限吗？我添加了读取外部存储和写入外部存储，我还需要什么吗@Ragnar您是否有错误日志，其中提到

无法打开文件

？
