Vuex: Firebase routing. If statement

I am using firestore for my project. I am using vuex, and I finished signIn mehod.

Now, I need the conditional branch.

Here is what I want to achieve.

If proUser collection has the field, "status" == true, the route is dashboard/products. And if the collection doesn't have "status" == true field, the route is selfonboarding.

But now, when I login as the user who has "status" == true field, I always go to /selfonboarding.

I cannot figure out why I cannot go to the dashboard/products.

This is my signIn method.

import 'firebase/firebase-auth'
import fireApp from '@/plugins/firebase'
import router from '../../router'
const firebase = require("firebase");
require("firebase/firestore");
const db = firebase.firestore();

const state = {
    currentUser: null
}

const getters = {
    currentUser: state => state.currentUser
}

const mutations = {
    userStatus: (state, user) => {
        // if(user) {
        //   state.currentUser = user
        // }
        // else {
        //   state.currentUser = null
        // }
        user === null ? state.currentUser = null : state.currentUser = user.email
      }
}

const actions = {
 signIn: async ({ commit }, user) => {
    try {
      const userData = await fireApp.auth().signInWithEmailAndPassword(
          user.email,
          user.password
      );

      var userStatus = fireApp.auth().currentUser;
        var userStatus = db.collection('ProUser').where("status", "==", true)
        userStatus.get().then((doc) => {
            if (doc.exists) {
                router.push("dashboard/products");
            } else {
                router.push("selfonboarding");
            }
        })
        
    }
    catch(error) {
        const errorCode = error.code
        const errorMesage = error.message
        if(errorCode === 'auth/wrong-password') {
            alert('wrong password')
        } else {
            alert(errorMesage)
            }
        }
    },
}

export default {
    state,
    mutations,
    getters,
    actions
}
