我有一個類似于以下內容的 JSON 響應：一個 Subscription POJO 類及其內部是“subscriptionPlans”的 Arraylist：訂閱詳細信息.java@Expose()@SerializedName("subscriptionPlans")public ArrayList<SubscriptionPlans> subscriptionPlans;public ArrayList<SubscriptionPlans> getSubscriptionPlans() {    return subscriptionPlans;}@Overridepublic String toString() {    return "SubscriptionDetails{" +            "subscriptionPlans=" + subscriptionPlans +            '}';}訂閱計劃.java@SerializedName("plan_name")@Exposepublic String planName;@SerializedName("description")@Exposepublic String description;@SerializedName("amount")@Exposepublic String amount;public String getPlanName() {    return planName;}public String getDescription() {    return description;}public String getAmount() {    return amount;}我正在使用 Gson 從 JSON 中獲取數據并將其填充到各種 POJO 類中，如下所示：Gson gson = new Gson();SubscriptionDetails subscriptionDetails = gson.fromJson(String.valueOf(jsonObject.getJSONArray("subscriptionPlans")), SubscriptionDetails.class);ArrayList<SubscriptionPlans> subscriptionPlans = subscriptionDetails.getSubscriptionPlans();String amount = subscriptionPlans.get(0).getAmount();但是，我收到錯誤響應， java.lang.IllegalStateException:Expected BEGIN_OBJECT but was BEGIN_ARRAY at line column 2 path $我在這里錯過了什么或做錯了什么？
