"Firebase ID token has invalid signature. See https://firebase.google.com/docs/auth/admin/verify-id-tokens for details on how to retrieve an ID token."

import { setAuthCookies } from "next-firebase-auth";
import initAuth from "../../../firebase/initAuth"; // the module you created above

initAuth();

export default async (req, res) => {
try {
await setAuthCookies(req, res);

} catch (error) {
res.status(400).send({ error: error.message, success: false });
}
};

Please HELP

It's hard to tell what's going wrong here without a clear way to reproduce it, so please share more info or a reproduction, if possible.

Here are a few things that might point you in the right direction:

• Double-check your Firebase config values are correct. See related docs on troubleshooting.
• Are you manually printing and verifying the token? Some people ran into this issue when copy-pasting a truncated token: Firebase ID token has invalid signature flutter/flutter#31635, Auth: GetToken() generates invalid token (Firebase ID token has invalid signature) firebase/firebase-cpp-sdk#3
• Maybe related to Handle additional errors from verifyIdToken #174: there are some errors this module doesn't handle but probably should.
• You could try logging and inspecting the JWT to try to identify what's wrong with its structure.

Hope this helps. Please follow up if you figure out what's going on.
