SSR not working

[abeltodev]

When I add the prerender property to the RecycleScroller I get these errors:

Parent: <div class="vue-recycle-scroller__item-wrapper" style="min-height:nullpx;">

Mismatching childNodes vs. VNodes:  
NodeList(20) [ div.vue-recycle-scroller__item-view, div.vue-recycle-scroller__item-view, div.vue-recycle-scroller__item-view, div.vue-recycle-scroller__item-view, div.vue-recycle-scroller__item-view, div.vue-recycle-scroller__item-view, div.vue-recycle-scroller__item-view, div.vue-recycle-scroller__item-view, div.vue-recycle-scroller__item-view, div.vue-recycle-scroller__item-view
, … ]
 
Array []

[Vue warn]: The client-side rendered virtual DOM tree is not matching server-rendered content. This is likely caused by incorrect HTML markup, for example nesting block-level elements inside <p>, or missing <tbody>. Bailing hydration and performing full client-side render.

Here is my code simplified

<script>

    export default {

        computed: {
            items() {
                return this.$store.state.items
            }
        },

        preFetch ({store}) {
            return Promise.all([
                store.dispatch('load')
            ])
        },

        mounted() {
            this.$store.dispatch('load')
        }
    };

</script>

<RecycleScroller
                    class="scroller"
                    :items="items"
                    :item-size="32"
                    key-field="id"
                    v-slot="{ item }"
                    :prerender="20"
                >
                    <div class="user">
                        {{ item.id }}
                    </div>
                </RecycleScroller>

Am I doing something wrong? I spent 2 days in it, but I'm unable to find a solution ...
