Vue Component Conditional Creation

I want to create a list of actions (each of which is a component) conditionally if the object variable store.plan is not empty, I have tried v-if which works well for rendering but not for creating the component.

I get an error:

Uncaught (in promise) TypeError: action is undefined

The full code of this component can be found here.

Can you please tell me how can I handle this problem? thanks in advance.

<template>
    <div class="planlist" v-if="parse">
        <ul id="planOl">
        <Action
        v-for="action in store.plan"
            :action_id="action.act_id"
            :actor="action.actor"
            :color="action.color"
            :size="action.size"
            :lego_name="action.lego"
            :pick_pos="action.pick"
            :place_pos="action.place"
            :blocked="action.blocked"
            :status="action.status"
            :key="action.act_id"
        />
        </ul>
    </div>
</template>

<script>
import Action from '../components/Action.vue';
import { store } from '../js/store.js'

export default {
    name: 'Plan', 
    data() {
        return {           
            store,
        }
    },
    computed: {
        parse() { 
            if (store.plan.length > 0) { 
                return true;
            }
            return false;
        }
    },
    components: {Action}
}
</script>
