vue-router4路由 No match found for location with path警告

目前页面访问不影响，我猜测是路由跳转的时候，还没有注入响应的路由，然后第二次访问时已经生成好路由了。
虽然可以正常访问页面，但这个报错看着很不舒服，有没有人知道咋解决的

//路由完全注册标识
let routeFlag = false
router.beforeEach((to, from, next) => {
    const hasToken = localStorage.getItem('token')
    if (hasToken) {
        if (routeFlag) {
            next()
        } else {
            // 注册动态路由
            store
                .dispatch('userModule/ASYNC_ROUTER')
                .then(() => {
                    genRouteConfig().then(() => {
                        routeFlag = true
                        next({ ...to, replace: true })
                    })
                })
                .catch(() => {
                    localStorage.removeItem('token')
                    next(`/login?redirect=${to.path}`)
                })
        }
    } 

//动态生成路由
const genRouteConfig = () => {
    const getMenus: newMenustype = store.getters['userModule/getMenus']

    return new Promise((resolve, reject) => {
        router.addRoute({
            path: '/:catchAll(.*)',
            redirect: '/404',
            name: 'NotFound'
        })
        for (let key in getMenus) {
            let menusObj = getMenus[key]
            const routerObj: RouteRecordRaw = {
                path: '/' + menusObj.name,
                name: menusObj.name,
                component: () => import('@/views/homepage/homepage.vue'),
                children: []
            }
            if (menusObj.children) {
                routerObj.redirect = `/${menusObj.name}/${menusObj.children[0].name}`
                for (let i = 0; i < menusObj.children.length; i++) {
                    let menuName: string = menusObj.children[i].name
                    if (routerObj.children) {
                        routerObj.children.push({
                            path: menuName,
                            name: menuName,
                            component: modules[`./views/${menusObj.name}/${menuName}.vue`]
                        })
                    }
                }
            }
            router.addRoute(routerObj)
        }
        resolve(true)
    })
}
