不变违规对象不能作为react子对象有效（发现：错误无效参数“ path”）

Question

实施“ react-native-fetch-blob”以在Firebase Storage中上传图像后，我遇到了这个问题。

我尝试从https://github.com/CodeLinkIO/Firebase-Image-Upload-React-Native运行代码。我的代码如下：

uploadImage(uri, mime = "image/jpg", userID) {
  return new Promise((resolve, reject) => {
    const uploadUri = uri;
    let uploadBlob = null;

    const imageRef = firebase
      .storage()
      .ref("images")
      .child(userID);

    fs.readFile(uploadUri, "base64")
      .then(data => {
        return Blob.build(data, { type: `${mime};BASE64` });
      })
      .then(blob => {
        uploadBlob = blob;
        return imageRef.put(blob, { contentType: mime });
      })
      .then(() => {
        uploadBlob.close();
        return imageRef.getDownloadURL();
      })
      .then(url => {
        resolve(url);
      })
      .catch(error => {
        reject(error);
      });
  });
}

但是我总是收到错误提示：

  

不变违反对象无效，不能作为react子对象（找到：错误无效参数“ path”）

有关此问题的任何帮助吗？

编辑 这是其他渲染代码。

编辑2

startSigningUp (email,password)
{
    firebase.auth().createUserWithEmailAndPassword(email, password).then(
        ()=> {

        const user = firebase.auth().currentUser;
        const userId = user.uid;

        this.setState({
            user
        })


        this.uploadImage(this.state.avatarUri.uri,userId).then((imageURL)=>{
            saveDatabase(userId,imageURL)
        }).catch((error)=>{
            this.setState({
                error,
                isLoading: false
            })
        })



        })

}
