Schema validation with Zod - Vue 3

Question

I use combobox from Shadcn-ui (https://www.shadcn-vue.com/docs/components/combobox#combobox) in my Nuxt 3 project. I cannot validate my combobox with zod. When I select an element and submit the form, I always get the error message "Account is required" which appears. No matter what I choose, the validation does not pass. Could someone help me find the problem please?

My code:

<script setup lang="ts">

const accounts = [
    { value: 'nuxt.js', label: 'Nuxt.js' },
    { value: 'remix', label: 'Remix' },
    { value: 'astro', label: 'Astro' },
]
const open = ref(false)
const value = ref('')

const formSchema = toTypedSchema(z.object({
    accountSelected: z.string({
        required_error: "Account is required"
    }),
    setupName: z.string({
        required_error: "Setup is required"
    })
}))

const form = useForm({
    validationSchema: formSchema,
})

const submitForm = form.handleSubmit((values) => {
    console.log("form submitted");
})
</script>

<template>

    <form @submit="submitForm">
        <FormField v-slot="{ componentField }" name="accountSelected">
            <FormItem class="flex flex-col">

                                    ? accounts.find((account) => account.value === value)?.label
                                    : "Select account..." }}

Try to set value manually as below:

@select="(ev) => {
  if (typeof ev.detail.value === 'string') {
    value = ev.detail.value
    form.setFieldValue('accountSelected', ev.detail.value)
  }
  open = false
}"
