I’ve tried to use the stepper component to create a stepper into my nuxt app.
The stepper is correctly loaded, but there is an error in the console : expose() should be called only once per setup(). But I haven’t used any expose() function.
By removing the UStepper component, everything works.
Here is my code :
<template>
<div class="w-screen bg-slate-100 dark:bg-slate-900">
<div class="container mx-auto py-12 mt-20">
<h2 id="working" class="text-center mb-20">How it works</h2>
</div>
</div>
</template>
<script setup lang="ts">
import type { StepperItem } from '@nuxt/ui';
const items = ref<StepperItem[]>([
{
title: 'Address',
description: 'Add your address here',
icon: 'i-lucide-house',
},
{
title: 'Shipping',
description: 'Set your preferred shipping method',
icon: 'i-lucide-truck',
},
{
title: 'Checkout',
description: 'Confirm your order',
},
]);
</script>
Here is the entire error :
WARN [Vue warn]: expose() should be called only once per setup().
