Missing setRequired(TRUE | FALSE) on field 'recaptcha' in form 'xxxForm'

[sallyx]

$form->addRecaptcha() shows reCaptcha, but not validate it.
$form->addRecaptcha()->setMessage('Are you bot?'); triggers warning "Missing setRequired(TRUE | FALSE) on field 'recaptcha' in form 'xxxForm'"
$form->addRecaptcha()->setRequired(FALSE)->setMessage('Are you bot?'); doesnt validate.
$form->addRecaptcha()->setRequired(TRUE)->setMessage('Are you bot?'); doesnt show 'Are you bot?' but 'This field is required' if form is submited without checking reCaptcha.

Could you try change this rule?

Maybe try combination with setOmitted().
