firebase函数在部署时出现无效的_参数HTTP错误400

Question

现在尝试解决Firebase实时数据库功能上的问题5个小时，请访问“Firebase部署”：

直到今天才有这个

功能是：

exports.makeUppercase = functions.database.ref('/userfollowers/{pushId}/followers')
    .onWrite((change, context) => {
      // Only edit data when it is first created.
      if (change.before.exists()) {
        return null;
      }
      // Exit when the data is deleted.
      if (!change.after.exists()) {
        return null;
      }
      // Grab the current value of what was written to the Realtime Database.
      const original = change.after.val();
      console.log('Uppercasing', context.params.pushId, original);
      const uppercase = original.toUpperCase();
      // You must return a Promise when performing asynchronous tasks inside a Functions such as
      // writing to the Firebase Realtime Database.
      // Setting an "uppercase" sibling in the Realtime Database returns a Promise.
      return change.after.ref.parent.child('uppercase').set(uppercase);
    });
which is straight out of documentation.

终端显示：

⚠  functions: failed to create function makeUppercase
HTTP Error: 400, The request has errors

在Firebase项目的functions文件夹中使用以下命令更新Firebase CLI和SDK：

npm install firebase-functions@latest firebase-admin@latest --save
npm install -g firebase-tools
