getValues('field') returns undefined combined with Form.List field array

Question

When combining getValues and Form.List, getValues('names') returns undefined instead of the array itself.

I also tried to setValue of the array on input change:

<Form.List>
   <Input onChange={(event) => {
      form.setValue('names['+field.key+']', event.target.value, { shouldValidate: true });
   }} />
</Form.List>
