Vue 3 Form Validation scenarios on Custom Input Component with V-Model Binding

vue vee-validate forms JavaScript

I'm optimizing some code but I've hit a wall trying to I'm working on a Vue 3 application and I've created a custom input component that uses `v-model`. The component looks like this: ```vue <template> <input type='text' :value='modelValue' @input='$emit("update:modelValue", $event.target.value)' /> </template> <script> export default { props: { modelValue: String } } </script> ``` In my parent component, I'm trying to implement form validation using VeeValidate. However, when I apply validation rules to this custom input, the validation seems to ignore the value that I input. Here's how I'm integrating it: ```vue <template> <Form @submit='handleSubmit'> <CustomInput name='username' v-model='username' /> <ErrorMessage name='username' /> <button type='submit'>Submit</button> </Form> </template> <script> import { defineComponent } from 'vue'; import { useForm, useField } from 'vee-validate'; import CustomInput from './CustomInput.vue'; export default defineComponent({ components: { CustomInput }, setup() { const { handleSubmit } = useForm(); const { value: username } = useField('username', 'required'); return { handleSubmit, username }; } }); </script> ``` When I try to submit the form, the validation message appears saying that the username is required even though I have entered a value. I inspected the `username` field in the Vue DevTools, and it shows that it is still empty. I made sure that my `CustomInput` is correctly emitting the updated value, but somehow it seems that the validation library isn't capturing it. I've checked the documentation for both Vue 3 and VeeValidate to ensure I'm not missing anything. Has anyone faced a similar scenario with custom components and v-model in forms? Any help would be greatly appreciated! What's the best practice here?
