Error: Call to a member function getFieldValue() on bool in vendor/magento/framework/App/PageCache/Kernel.php:134

I was getting this error when sending response to the get type ajax controller.

the code was like below.

<?php

declare(strict_types=1);

namespace VendorModuleControllerIndex;

use MagentoFrameworkAppActionHttpGetActionInterface;
use MagentoFrameworkAppResponseHttp;
use MagentoFrameworkControllerResultInterface;
use MagentoFrameworkExceptionLocalizedException;
use MagentoFrameworkSerializeSerializerJson;
use MagentoFrameworkViewResultPageFactory;
use PsrLogLoggerInterface;

class Download implements HttpGetActionInterface
{


    protected $resultPageFactory;

    protected $serializer;

    protected $logger;

    protected $http;

    public function __construct(
        PageFactory $resultPageFactory,
        Json $json,
        LoggerInterface $logger,
        Http $http
    ) {
        $this->resultPageFactory = $resultPageFactory;
        $this->serializer = $json;
        $this->logger = $logger;
        $this->http = $http;
    }


    public function execute()
    {
        try {
            return $this->jsonResponse('your response');
        } catch (LocalizedException $e) {
            return $this->jsonResponse($e->getMessage());
        } catch (Exception $e) {
            $this->logger->critical($e);
            return $this->jsonResponse($e->getMessage());
        }
    }

    public function jsonResponse($response = '')
    {
        $this->http->getHeaders()->clearHeaders();
        $this->http->setHeader('Content-Type', 'application/json');
        return $this->http->setBody(
            $this->serializer->serialize($response)
        );
    }
}
?>
