Test Cannot destructure property

[lumos94]

The below test returns the following error:
TypeError: Cannot destructure property 'isSubmitting' of 'undefined' as it is undefined.

I haven't found anything related to this kind of error. Should I inject isSubmitting somehow in the test?

//Form.vue

<VeeForm @submit="onSubmit" v-slot="{isSubmitting}"> //VeeField </VeeForm>

//form.test.js

import Form from "@/components/Forms/Form.vue";
import {expect, test} from "vitest";

test("mount component", async () => {
    expect(LoginForm).toBeTruthy();
    mount(LoginForm);
})

No idea, are you shallow rendering or stubbing the form component? Provide a minimal test repo and I can take a look.
