How to replicate it?

import database from '@react-native-firebase/database';

const customHook = () => {
  useEffect(() => {
    // Set promise never resolves!!
    database().ref('/live_users/<USER_ID>')
      .set({ date: new Date() })
      .them(() => console.log("success"))
      .catch(() => console.log("error"))
  },[]);
}

How to solve it?

You need to get the database reference from the app.

import { firebase } from '@react-native-firebase/database';

const customHook = () => {
  useEffect(() => {
    // Now set call should work
    firebase
      .app()
      .database()
      .ref('/live_users/<USER_ID>')
      .set({ date: new Date() })
      .them(() => console.log("success"))
      .catch(() => console.log("error"))
  },[]);
}
