Research direction

Start by reproducing the failure from the generateVerifyAndChangeEmailLink entry point using the TypeScript example and the stated Firebase SDK version. Trace the Admin Node.js Auth implementation and its email-action-link request; done means changing a user's email produces a link instead of auth/internal-error.

Description

api: auth
Describe your environment
  • Operating System version: _____
  • Firebase SDK version: 13.2.0
  • Firebase Product: auth
  • Node.js version: 22.14.0

Describe the problem

generateVerifyAndChangeEmailLink stopped working. Unfortunately I was unable trace what caused it to stop working.

When running following code to change a users email I get following error:
FirebaseAuthError: INTERNAL ASSERT FAILED: Unable to create the email action link

{
  errorInfo: {
    code: 'auth/internal-error',
    message: 'INTERNAL ASSERT FAILED: Unable to create the email action link'
  },
  codePrefix: 'auth'
}
Steps to reproduce:

Create firebase auth user with password and email.
Try to change the email of the user using generateVerifyAndChangeEmailLink

Relevant Code:
import admin from "firebase-admin";

const serviceAccountDev = require("../keys/developmentKey.json");

admin.initializeApp({
  credential: admin.credential.cert(serviceAccountDev),
});

const changeMail = async (email: string, newEmail: string) => {
  const changeMailLink = await admin
    .auth()
    .generateVerifyAndChangeEmailLink(email, newEmail);
  console.log("changeMailLink", changeMailLink);
};
