I'm migrating some code and I'm learning this framework and I've been struggling with this for a few days now and could really use some help. I've been banging my head against this for hours. I'm working on a Vue 3 application and I'm working with an scenario with form submission when using v-model alongside the VeeValidate library for form validation. I want to prevent the form from submitting if there are validation errors, but the form appears to submit regardless, and I'm getting an behavior in the console: `Uncaught (in promise) behavior: Validation failed`. Here's a simplified version of my form component: ```vue <template> <form @submit.prevent="handleSubmit"> <input v-model="formData.email" type="email" name="email" /> <span v-if="errors.email">{{ errors.email }}</span> <button type="submit">Submit</button> </form> </template> <script> import { ref } from 'vue'; import { useForm } from 'vee-validate'; export default { setup() { const { handleSubmit, errors } = useForm({ validationSchema: /* validation schema here */, }); const formData = ref({ email: '', }); const submitForm = (values) => { console.log('Form submitted:', values); }; return { formData, handleSubmit: handleSubmit(submitForm), errors }; }, }; </script> ``` I've tried using `@submit.prevent="handleSubmit"` but it doesn't seem to be preventing the default behavior correctly. I checked the VeeValidate documentation, and it suggests that the `handleSubmit` function should take care of managing the form submission, but it’s not working as expected. I also ensured that the validation schema is correctly set up, but I'm still seeing the console behavior. Does anyone have suggestions on how to properly handle the form submission and prevent it when validation fails? Any insights or examples would be greatly appreciated! Am I missing something obvious? I'm working on a CLI tool that needs to handle this. Thanks in advance! This is for a desktop app running on Ubuntu 22.04. I'm coming from a different tech stack and learning Javascript.
