调用官方提供的联系人jar获取方法, 报空指针异常

调用官方的联系人sdk查询联系人, 报空指针异常;
目标手机联系人数量比较多, 大概20k左右; 接口效率很慢, 同时在报错;
大概调用方法如下:

plus.contacts.getAddressBook(plus.contacts.ADDRESSBOOK_PHONE, book => {  
      // 可通过addressbook进行通讯录操作  
      book.find(contactFields, list => {  
        const queryFinishTime = new Date().getTime();  
        const rst = dealData(list);  
        const now = new Date().getTime();  
        logger.info(`Query contact finish! count: ${rst.length}, ` +  
          `query cost: ${queryFinishTime - startTime}, ` +  
          `deal cost: ${now - queryFinishTime}ms, ` +  
          `total cost: ${now - startTime}ms`);  
        resolve(rst);  
      }, (e) => {  
        logger.error("Failed to get contacts:" + e.message);  
        resolve([]);  
      }, findOpts)  
    }, e => {  
      logger.error("Failed to get address book: " + e.message);  
      resolve([])  
    });

crash日志如下:
