Hello just found this npm package and i wanted to test but unfortunately i cant use it from strange error that it comes from LazyHydrate.js:339:31

<LazyHydrate when-visible>
         <post-list v-if="posts && !isLoading" :posts="posts" title="Recent Posts"></post-list>
       </LazyHydrate>

And it gives me error Cannot read property '0' of undefined the error cames from here

render: function render(h) {
      var tag = this.$el ? this.$el.tagName : "div";
      var child = this.$scopedSlots.default ? this.$scopedSlots.default({
        hydrated: this.hydrated
      }) : this.$slots.default[0]; // This line causes error
      var vnode = this.hydrated ? child : h(tag); // Special thanks to Rahul Kadyan for the following lines of code.

Try to change your code to:
<LazyHydrate when-visible v-if="posts && !isLoading"> <post-list :posts="posts" title="Recent Posts"></post-list> </LazyHydrate>
