unittesting vue3-recaptcha-v2, "Cannot set properties of null"

[jamercee]

For the life of me, I can't figure out how to erect a unit test harness for a project that includes vue3-recaptcha-v2. I know it's something I'm missing, but was hoping someone could point me in the right direction.

Simple app, which works fine:

<script setup>
import { ref } from "vue"
import { VueRecaptcha } from "vue3-recaptcha-v2"
const recaptchaWidget = ref(null)
</script>

<template>
<vue-recaptcha @widget-id="recaptchaWidget = $event" />
</template>

Unit test:

import { describe, it } from 'vitest'
import { mount, config } from '@vue/test-utils'
import VueRecaptcha from 'vue3-recaptcha-v2'
import App from '../App.vue'

config.plugins.VueWrapper.install(VueRecaptcha, { siteKey: 'fake-key'})

describe('App test', () => {
  it('mount properly', () => {
    mount(App)
  })
})

A run of npm run test:unit

Yields the error:

stderr | src/__tests__/App.test.js > App test > mount properly
