我收到此错误。我已成功将图像添加到存储并获取 URL，但当我想将文档添加到我的收藏夹时，我收到此错误。我正在以与 Firebase 相同的方式实现代码，此处为 addDoc => 的参考 https://firebase.google.com/docs/firestore/manage-data/add-data#web-version-9_1

admin:1 Uncaught (in promise) FirebaseError: Expected type 'Na', but it was: a custom an object

uploadTask.on(
  "state_changed",
  (snapshot) => {
    setProgress((snapshot.bytesTransferred / snapshot.totalBytes) * 100);
    console.log();
  },
  (error) => {
    console.log(error);
  },
  () => {
    // Get ImageURL
    getDownloadURL(uploadTask.snapshot.ref).then((downloadURL) => {
      setImgURL(downloadURL);
      // Add new collection document to FIREBASE
      addDoc(portfolioItemsCol, {
        img: downloadURL,
        title: title,
      })
        .then((docRef) => {
          console.log("Document succesfully Added");
        })
        .catch((err) => console.log(err));
    });
  }
);
