javascript - 上传两张图片时，console.log(parsedRes) 只返回一个对象而不是（预期的）两个

Question

所以，我试图从我上传到云/服务器的两个图像中获取 base64 数据（url），但是当我解析响应时，我只得到 1 个对象而不是 2 个（即只有第一个图像的 url）。

我必须从根本上监督某些事情，但我看不到它。欣赏建议。

有人能帮我解释一下为什么下面的代码不起作用吗？

[编辑：我已经包含了服务器代码。希望这可以让我更清楚地了解我面临的问题]

    .then(token => {
        authToken = token;
        return fetch("myappURL/storeImage", 
        {
            method: "POST",
            body: JSON.stringify({ 
                image: image.base64,
                coverImage: coverImage.base64
            }),
            headers: { Authorization: "Bearer " + authToken }
        });
    })
    .catch(err => {
        console.log(err);
        alert("Oops! Something went wrong, please try again1")
        dispatch(uiStopLoading());
    })
    .then(res => {
        if (res.ok) {
            return res.json();
        } else {
            throw(new Error());
         }
    })
    .then(parsedRes => {console.log(parsedRes)}); // I only get 1 result instead of 2 (why?!)

服务器端代码：

exports.storeImage = functions.https.onRequest((request, response) => {
return cors(request, response, () => {....
.then(decodedToken => {
      const body = JSON.parse(request.body);
      fs.writeFileSync("/tmp/uploaded-image.jpg", body.image, "base64", err => {
        console.log(err);
        return response.status(500).json({ error: err });
      });
      const bucket = gcs.bucket("myapp.appspot.com");
      const uuid = UUID();

      return bucket.upload(
        "/tmp/uploaded-image.jpg",
        {
          uploadType: "media",
          destination: "/places/" + uuid + ".jpg",
          metadata: {
              metadata: {
                  contentType: "image/jpeg",
                  firebaseStorageDownloadTokens: uuid
              }
          }
        },
        (err, file) => {
          if (!err) {
            return response.status(201).json({  // I get this returned
              imageUrl:
                "https://firebasestorage.googleapis.com/v0/b/" +
                bucket.name +

                uuid,

            });
          } else {
            console.log(err);
            return response.status(500).json({ error: err });
          }
        }
      );
  })
  .catch(error => {

    response.status(403).json({error: "Unauthorized"});

.then(decodedToken => {

        return response.status(500).json({ error: err });
      });
      const bucket = gcs.bucket("myapp.appspot.com");
      const uuid = UUID();

      return bucket.upload(
        "/tmp/uploaded-coverImage.jpg",
        {
          uploadType: "media",
          destination: "/coverPlaces/" + uuid + ".jpg",
          metadata: {
              metadata: {
                  contentType: "coverImage/jpeg",

              }
          }

        (err, coverFile) => {
          if (!err) {
            return response.status(201).json({  // I do NOT get this returned (why not?!)
              coverImageUrl:

                uuid,
              coverImagePath: "/coverPlaces/" + uuid + ".jpg"
            });
          } else {
            console.log(err);
            return response.status(500).json({ error: err });
