Please add following code in your controller :

protected $request;
protected $formKey;

public function __construct(
\Magento\Framework\App\Action\Context $context,
\Magento\Framework\Data\Form\FormKey $formKey,
\Magento\Framework\App\Request\Http $request
) {
    $this->request = $request;
    $this->formKey = $formKey;
    $this->request->setParam('form_key', $this->formKey->getFormKey());

  • Doesn't this simply disable the form key validation instead of fixing the cause of the missing form key?
