IBM JSON Parser错误

Question

我正在使用IBM MFP8安全检查适配器。用户通过身份验证后，我的后端服务将在JSONObject中提供用户数据，并将该用户数据作为字符串存储在属性中。在另一个适配器中，我调用此用户数据并尝试再次解析为JSONObject并在将字符串解析为JSONObject时出现波纹错误。请帮助确定问题的位置以及如何解决此问题。

代码：

import com.ibm.json.java.JSON;
import com.ibm.json.java.JSONArray;
import com.ibm.json.java.JSONObject;

AuthenticatedUser user = securityContext.getAuthenticatedUser();            
String queryParams = (String) user.getAttributes().get("queryParams");
JSONObject queryParamsObject = (JSONObject) JSON.parse(queryParams);

错误：
