How to open the default page in the Bitrix24 application on vuejs with Router?

Question

Bitrix24

Good afternoon. There is an application in Bitrix24 on vuejs, the transition between components is made through vue Router. Everything works, but when the application starts, the default component does not open.
Router settings:

import Vue from 'vue'
import Router from 'vue-router'

import activeTasks from '../components/activeTasks'
import taskForDay from '../components/taskForDay'

Vue.use(Router)

export default new Router({
    mode: 'history',
    routes: [
        {
            path: '/',
            component: activeTasks
        },
        {
            path: '/taskForDay',
            component: taskForDay
        }
    ]
})

In App.js

<b-navbar type="dark" variant="primary" class="mb-2">
            <b-navbar-nav>
                <b-nav-item to="/" active-class="active" exact>Активные задачи</b-nav-item>
                <b-nav-item  to="/taskForDay" active-class="active">Задачи на день</b-nav-item>
            </b-navbar-nav>
        </b-navbar>
        <router-view></router-view>
