在core event的online方法中使用bot.getGroupList()返回值为null

[cold233]

详细描述
环境：Ubuntu 24.04 LTS (GNU/Linux 6.8.0-41-generic x86_64)

Java 版本：
openjdk 21.0.4 2024-07-16
OpenJDK Runtime Environment (build 21.0.4+7-Ubuntu-1ubuntu224.04)
OpenJDK 64-Bit Server VM (build 21.0.4+7-Ubuntu-1ubuntu224.04, mixed mode, sharing)

OneBot协议实现：
Lagrange.OneBot

Shiro版本：2.3.1

为了在机器人上线时更新机器人所在的所有群的信息并获取机器人自身角色，在Core Event中重写了online(Bot bot)方法，并在其中使用了如下代码获取群列表：
List<GroupInfoResp> groupInfos = bot.getGroupList().getData();
编译运行后日志显示该行代码中getGroupList()返回了null

日志如下：

使用wscat发送get_group_list请求结果如下（隐藏了QQ号及群号）：

预期结果
返回群列表

当前结果
返回了null

在最新的RELEASE版本中能否复现？
是

复现方法
在online(Bot bot)中使用bot.getGroupList()

这应该是一个需要被修复的问题，需要等有时间看看。
