I had the same problem today. You need to sanitize the read private key by replacing \\n characters with \n.

admin.initializeApp({
  credential: admin.credential.cert({
    "projectId": process.env.FIREBASE_PROJECT_ID,
    "private_key": process.env.FIREBASE_PRIVATE_KEY.replace(/\\n/g, '\n'),
    "clientEmail": process.env.FIREBASE_CLIENT_EMAIL,
  }),
  databaseURL: process.env.FIREBASE_DATABASE_URL,
});
