Firebase fails to fetch a valid Google OAuth2 access token on Windows

• Operating System version: Windows 10
• Firebase SDK version: no SDK used
• Library version: firebase-admin@6.4.0
• Firebase Product: Realtime database

[REQUIRED] Step 3: Describe the problem

I built a script to download data from the Realtime database, on Mac. Here things work fine. But when tested the script on Windows I get the following error:

@firebase/database: FIREBASE WARNING: {"code":"app/invalid-credential","message":"Credential implementation provided to initializeApp() via the \"credential\" property failed to fetch a valid Google OAuth2 access token with the following error: \"Failed to parse access token response: Error: Server responded with status 400.\"."}

Steps to reproduce:

Build a script that access data from Realtime database, using firebase-admin. Run it on Windows.

Relevant Code:

var admin = require("firebase-admin");
var serviceAccount = require("./adminsdk.json");
admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: "https://<project-id>.firebaseio.com"
});
var db = admin.database();
var dataRef = db.ref("ref");
