RemoteWebDriver调用Selenium BiDi组件失败，寻求社区协助

我的代码在本地ChromeDriver实例上运行正常，WebDriver BiDi协议功能完全可用。但切换为连接Selenium Grid/Server的RemoteWebDriver实例时，抛出错误：

java.lang.IllegalArgumentException: WebDriver instance must support BiDi protocol

我已编写基础测试，通过设置webSocketUrl capability构造ChromeDriver，可成功实例化JSFatalCatch工具类并初始化LogInspector，本地测试全部通过。

排查情况 #

• 本地ChromeDriver场景：Driver实例包含biDiUri和BiDi实例，说明WebDriver BiDi连接已成功建立，LogInspector等BiDi API可正常使用。
• RemoteWebDriver连接Grid场景：Driver的Capabilities中存在se:bidi字段，但仍抛出不支持BiDi的错误，排除代码本身问题，怀疑是Selenium Server(Grid)的配置问题。

以下是测试代码及Driver Capabilities信息，恳请社区协助解决：
