I also have this error.
I investigate a bit.
When the form is first build (function initializeFormStateFromRequest() in FormRuntime.php), the formState is empty, and therefore also the "formValues" array.
The variants are then evaluate, with an empty formValues array.
I gess variants based on formValues should be evaluated only on form submission?
