Need help with Vuetify/Vee-Validate/Yup

Hello,
I have followed the Validation Forms course and created a form. I am confused on how to validate an array element and will truly appreciate your help. When I multi-select, the values are not reflected in modelValues.

I have a combo box.

<v-combobox
:id=“uuid”
:aria-describedby=“error ? ${uuid}-error : null”
:aria-invalid=“error ? true : null”
:items=“options”
:model-value=“modelValue”
dense
item-title=“v”
item-value=“k”
multiple
persistent-hint
return-object
v-bind="{
…$attrs,
}"
@update:model-value=“updateValue”>

I am then using vee-validate useFieldArray to bind the element to the combo box.
const { fields: myField } = useFieldArray(‘myField’)

Yup validation schema has the following annotation
myField: array().of(string()),
