The "form" extension is not enabled

Question

"form" extension is not enabled

I got the above error when i override listAction of Sonata Admin Bundle.

Could someone have the same problem ?

Answer 1

Use $twig->getExtension(FormExtension::class) instead of $twig->getExtension('form') where FormExtension is included by use Symfony\Bridge\Twig\Extension\FormExtension;
