Firebase service account does not work anymore on localhost

[Mustafa Ekim]

Hi,

We have been actively using firebase since 2019. Today, without any apparent reason, the way we use to authentication for firebase on localhost started to throw error:

• "Error: 16 UNAUTHENTICATED: Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential."

Below is the code we have been using since 2019.

var remoteConfig = {

  credential: admin.credential.cert(serviceAccount as admin.ServiceAccount),

  databaseURL: "XXX",

  storageBucket: "XXX"

}

admin.initializeApp(remoteConfig);

This error may have started to be thrown after I've updated windows but first I am not sure if these are related and second I have no idea about how to fix this.

I've spent a few hours on this but I could not find so much. Anybody has a guess on this bizarre situation?

I am 99% sure that the problem is not related to codes but any suggestion would be appreciated.

Thanks

Check if you've authorized your domain at firebase authentication Tab.

If you didn't add your domain to this section, all requests made to firebase auth will be rejected.

Hi,

Thanks for the suggestion. Both localhost and our domain are listed as Authorized domain.

Hi Mustafa,

It sounds like the service account you're using locally is no longer valid. Since you mentioned that you recently updated your machine, maybe the key file got moved around or corrupted somehow?  Or maybe someone invalidated it remotely from the console.

The simplest thing to do would be to follow the instructions to download a new one and try using that;

Hello Sam,

Thanks. Actually I created another key under the same service account however that did not help. 

Maybe I should also add that

• I am using a service account created under google cloud iam - not firebase console.
• I have another windows machine which continues working fine using the same service account json.

what type of auth method are you using?

Hi, we are using the firebase-admin library. I don't know what it uses behind the scenes.

import * as admin from "firebase-admin";

var serviceAccount = {

  "type": "service_account",

  "project_id": "xxx",

  "private_key_id": "xxxx",

  "private_key": "xxx",

  "client_email": "xxx",

  "client_id": "xxx",

  "auth_uri": "xxx",

  "token_uri": "xxx",

  "auth_provider_x509_cert_url": "xxx",

  "client_x509_cert_url": "xxx"

}

var remoteConfig = {

credential: admin.credential.cert(serviceAccount as admin.ServiceAccount),

  databaseURL: "xxx",

  storageBucket: "xxx"

}

admin.initializeApp(remoteConfig);

  Wow. I've finally found the issue. If you set up your computer's time manually (I had adjusted the time to 2 hours later for some tests) firebase login does not work!

Thanks for sharing the solution Mustafa! I don't think I ever would have guessed that.
