I have made button New Comment as well as controller NewComment.php.

When I try to redirect to controller I have ERR_TOO_MANY_REDIRECTS.

This is my button block code:

namespace Vendor\Module\Block\Adminhtml\Category\Edit;

use Magento\Framework\View\Element\UiComponent\Control\ButtonProviderInterface;
use Magento\Cms\Block\Adminhtml\Page\Edit\GenericButton;

class NewCommentButton extends GenericButton  implements ButtonProviderInterface

public function getButtonData()
    return [
        'label' => __('New Comment'),
        'class' => 'save primary',
        'sort_order' => 90,
