在调用put（）到Firebase时反应本机未知错误

Question

Simulator screenshot

HandleUpload = () => {
if (this.state.video.uri) {
  console.log("Uploading")
  const fileExtension = this.state.video.uri.split('.').pop();

  let uuid = generateUUID();
  
  const fileName = `${uuid}.${fileExtension}`;
  console.log(fileName);
  
  let storageRef = firebase.storage().ref(`Posts/video/${fileName}`);

  storageRef.put(this.state.video.uri);

} else {
  console.log("Nothing is selected");
  return
}

}

每当我尝试运行这段代码时，该程序都会在上面显示的屏幕截图中遇到未知错误。可能是什么问题？
