I dynamically get menu information from the background, and then dynamically load the route after processing, but the page is loaded with a blank for the first time and can only be refreshed once. The code is as follows. Please take a look at where the problem is.

store.dispatch("GenerateRoutes").then((res) => { // roles
    if(res.data){
        console.log(store.getters.addRouters,"testrouter")
        router.addRoutes(store.getters.addRouters) // 
        setlocalExpirytime.setAge(1*60*1000).set("routertime")
        next({ ...to, replace: true }) // hack addRoutes ,set the replace: true so the navigation will not leave a history record
    }else{
        iView.Modal.warning({
            title: "",
            content: res.info,
            onOk(){
                store.dispatch("LogOut").then((res) => {
                    location.reload();
                    console.log(res,"logout")
                }).catch(err=>{
                    console.log(err,"logout")
                });
            }
        });
    }
}).catch((err)=>{
      console.log(err,"routererr")
})
