Custom error in controlled input

[hornta]

It would be nice for a way to tell RHF a controlled input control is failing validation so that I can't submit unless I fix the error. The only way to use the setError now is via the register function but I'm using the useController.

<Controller
  rules={{
    required: true,
    validate: value => validateField(value)
  }}
/>
