错误：Reference.update失败：第一个参数包含未定义的属性“ myposts.LKzKFGtFnfMGhudzBbFLoOGZ7Q42.-LTegs9RGVV-N8MKN8-8.fileUrl”

Question

但它已经全部上传到我的Firebase存储中，但是我无法通过配置文件创建新数据库

myfire.service.ts

handleImageUpload(data){
const user = this.user.getProfile();

const newPersonalPostKey = 
firebase.database().ref().child('myposts/').push().key;
const personalPostDetails = {
  fileUrl: data.fileUrl,
  name: data.fileName,
  creationDate: new Date().toString()
};


const updates = {};
updates['/myposts/' + user.uid + "/" + newPersonalPostKey] = personalPostDetails;

return firebase.database().ref().update(updates);
}

post.component.ts

this.myFire.handleImageUpload(data);
