An indescribable error was encountered while updating the vue-router view

has anyone ever encountered this situation?
how to Debug?
originally there is no problem, but after adding delay routing animation, we can see that there is a problem

      <transition name="slide-fade">
        <router-view></router-view>
      </transition>
      
  .fade-enter-active, .fade-leave-active {
  transition: opacity .5s;
}
.fade-enter, .fade-leave-to /* .fade-leave-active below version 2.1.8 */ {
  opacity: 0;
}

resolved, vue transition has a transition mode that can solve this problem

<transition name="fade" mode="out-in">
  <!-- ... the buttons ... -->
</transition>
