React-hook-form: isValid unexpectedly evaluates to false when using nested objects

[chriscarrillo]

Bug Overview
I have dateOfBirth.month, dateOfBirth.day, and dateOfBirth.year. The register options say all items are required. After completing the form, all fields have a value and formState.touched includes all items are touched, but isValid is false. If you look at the errors of the form, you can see an error for dateOfBirth.

To Reproduce...

1. Create a form with some inputs having the name of a nested object.
2. Set the submit button's disabled state to !isValid.
3. Observe the behavior.

Codesandbox
I have created a Codesandbox to reproduce the bug. The console.log's will help you see the issue more clearly.

Expected Behavior:
dateOfBirth should not be listed in the errors of the form. If the error is set to undefined, isValid should be true.
