Encountered an issue while mounting Vue component that was attempting to loop through itself: Component could not be mounted due to

Struggling to solve this particular issue. I have a primary wrapper element that utilizes another element to display the navigation structure.

The navigation can have multiple levels, so it needs to be dynamically generated.

This is how the wrapper looks:

<template>
    <nav v-if="this.navigation.length">
        <link-role :collection="navigation"></link-role>
    </nav>
</template>
<script>
    import LinkRole from './Formats/LinkRole';
    export default {
        components: {
            'link-role': LinkRole,
        },
        props: {
            navigation: {
                type: Object,
                default: () => { return {} }
            }
        }
    }
</script>

and the LinkRole component like this:

<template>
    <ul>
        <li v-for="(item, index) in collection" :key="index">
            <a v-if="item.url" :href="item.url" v-text="item.name"></a>
            <span v-else v-text="item.name"></span>
            <link-role v-if="item.items" :collection="item.items"></link-role>
        </li>
    </ul>
</template>
<script>
    import LinkRole from './LinkRole';
    export default {
        components: {
            'link-role': LinkRole,
        },
        props: {
            collection: {
                type: [Object, Array],
                default: () => []
            }
        },
    }
</script>

Within the LinkRole component, I'm iterating over items in the collection and recursively using LinkRole if there are more items at another level.

However, I'm encountering the following warning message:

[Vue warn]: Failed to mount component: template or render function not defined.

I'm struggling to determine the cause of this error. Any insights would be greatly appreciated.

The documentation states that in order to use a component recursively, you must include a name option within the component.

Components are able to call themselves recursively within their own template, but this can only be done by utilizing the name option.

import LinkRole from './LinkRole';
export default {
    name: 'link-role',
    components: {
        'link-role': LinkRole,
    },
    props: {
        collection: {
            type: [Object, Array],
            default: () => []
        }
    },
}
