Question

我正在尝试使用带有Async / Await的功能来建立与Firebase实时数据库的简单连接以减少代码，即使您使用try / catch包装代码，它仍然会引发以下错误。

exports.createBlogPost = functions.https.onRequest(async (req, res) => {
  try {
    cors(req, res, () => { });
    const response = req.body;
    response.createDate = new Date();
    const snapshot = await admin.database().ref(BLOG_POSTS).push(response);
    console.log("SNAP", snapshot.getKey());
    response.id = snapshot.getKey();
    res.send(response);
  } catch (e) {
    res.status(500).send(e);
  }
});

它在数据库中创建实例，但是我收到以下警告：
