Code

public function onResponse(ResponseEvent $event) {
    $request = $event->getRequest();
    if ($request->getRequestFormat() !== 'api_json') {
        return;
    }
    // At this point, we've already run validation on the request by checking
    // the query arguments. This means that if the query arguments change, we
    // may need to run this validation again. Therefore, all responses need to
    // vary by url.query_args.
    $response = $event->getResponse();
    if ($response instanceof CacheableResponseInterface) {
        $response->addCacheableDependency((new CacheableMetadata())->addCacheContexts([
            'url.query_args',
