Firebase Admin SDK NodeJS - “没有与提供的标识符相对应的用户记录。”错误

Question

按照 https://firebase.google.com/docs/auth/admin/email-action-links#generate_email_verification_link 上的 Firebase SDK 文档并得到以下错误，这没什么意义，因为该函数是使用经过身份验证的 admin.auth() 从服务器环境触发的。

有人知道是什么原因造成的吗？

Error from admin.auth().generateEmailVerificationLink : { Error: There is no user record corresponding to the provided identifier.
    at FirebaseAuthError.FirebaseError [as constructor] (/srv/node_modules/firebase-admin/lib/utils/error.js:42:28)

  errorInfo: 
   { code: 'auth/user-not-found',
     message: 'There is no user record corresponding to the provided identifier.' },
  codePrefix: 'auth' }

代码是这样的：

exports = module.exports = functions.firestore
  .document("xxx/{docId}")
  .onCreate(async (snap, context) => {
    let yyy = snap.data();
    let { uid, userData } = yyy;
    console.log("from sendEmailVerification, uid, userdata: ", userData);
    const actionCodeSettings = {
      url: `${emailConfirmationUrl}`,
      handleCodeInApp: false
    };
    return admin.auth().generateEmailVerificationLink(userData.email, actionCodeSettings)
      .then(async (link) => {
        console.log("uid from generateEmailVerificationLink and email: ", uid, userData.email)
        await admin.firestore().collection('users').doc(uid).set({
          verificationLink: link,
          emailVerified: false
        }, { merge: true });
        return emailfunc.sendCustomVerificationEmail(userData.email, link);
      })
      .catch((err) => {
        console.error("Error from admin.auth().generateEmailVerificationLink :", err);
        return Promise.reject(err);
      });
  });

您从数据库 (Firestore) 中读取了用户的电子邮件地址。但是，该用户帐户在 Firebase 身份验证中不存在。如果您希望使用像 getUser() 和 generateEmailVerificationLink() 这样的 API，它也必须存在于 Firebase Auth 中。仅在 Firestore 中拥有它是不够的。
