Error getting / creating a webwook

ManageWebhooksApi.getWebhookSubscriptionsByOrg と、スタックトレースに示されている ApiClient.deserialize のパスから始めます。Webhook サブスクリプション呼び出しで想定されるレスポンスの形状と、API が返すオブジェクトを比較します。リクエストが Gson の BEGIN_ARRAY/BEGIN_OBJECT エラーで失敗しなくなれば完了です。

This is my code for getting my organization webhooks

package com.primenet.cardprocessor.services;

import Api.ManageWebhooksApi;
import Invokers.ApiClient;
import com.primenet.cardprocessor.configs.CardProperties;
import lombok.RequiredArgsConstructor;
import lombok.SneakyThrows;
import lombok.extern.slf4j.Slf4j;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Service;

@Service
@RequiredArgsConstructor
@Slf4j
public class WebhookService {

private final CardProperties cardProperties;
private final ApiClient apiClient;

@SneakyThrows
public ResponseEntity<?> getWebhooks(){

    var organizationId = cardProperties.getMerchantId();
    var productId = "recurringBilling";
    var eventType = "rbs.subscriptions.charge.created";

    ManageWebhooksApi apiInstance = new ManageWebhooksApi(apiClient);
    var result = apiInstance.getWebhookSubscriptionsByOrg(organizationId, productId, eventType);

    return ResponseEntity.ok("wow");
}

}

This is the error i am getting
