Symfony3 Form Error - A form with an empty name cannot have a parent form

My code was working fine, util this morning, I got error 

[2018-08-17 12:39:42] request.INFO: Matched route "white_label_homepage". {"route":"white_label_homepage","route_parameters":{"_controller":"Bundle\\WhiteLabelBundle\\Controller\\DefaultController::indexAction","_route":"white_label_homepage"},"request_uri":"http://symfony/white-label","method":"GET"} []
[2018-08-17 12:39:42] request.CRITICAL: Uncaught PHP Exception Symfony\Component\Form\Exception\LogicException: "A form with an empty name cannot have a parent form." at /home/symfony/vendor/symfony/symfony/src/Symfony/Component/Form/Form.php line 270 {"exception":"[object] (Symfony\\Component\\Form\\Exception\\LogicException(code: 0): A form with an empty name cannot have a parent form. at /home/symfony/vendor/symfony/symfony/src/Symfony/Component/Form/Form.php:270)"} []

I don't wanna past the all code, but there is no explanation for this error nowhere to be found on internet :). So if someone can please elaborate what is this error mean. In docs there is no setting a name for a form, and there is no parent, so what is this error all about?

Happens if you accidently pass an empty string to the form builder's add() method like in the following example:

$builder->add('');
