Vue 3 + Vee-validate 4 - handleSubmit does not getting triggered

I am new to Vue and learning Vue using composition API. Now I am stuck on the validation and form submitting process. I am using VeeValidate for validation and form submission. I am handleSubmit function for form submission, but this is not getting triggered at all.

I have tried creating the form as per the documentation but how I messed up. Any help would be appreciable

The actual problem with PrimeVue dropdown control. It was not showing the error message. When I checked the whole form then I clearly found the issue which was an invalid value. As value was in object and declare it a string in yup object.
