jmeter 设置代理选项时，Selenium节点的toml配置不起作用

我正在拼命尝试启动一个Selenium节点（Selenium standalone 4.13.0），以便使用远程Linux vm通过jmeter/jmeter-server工具（通过rmi）运行一些性能测试。我必须使用自定义代理设置启动firefox的会话，所以我尝试启动selenium节点，包括CL中的toml配置文件的引用。
我这样写这个文件，试图正确插入设置代理所需的内容：

[node]
detect-drivers = false

[[node.driver-configuration]]
display-name = "firefox"
stereotype = "{\"browserName\": \"firefox\", \"browserVersion\": \"118\", \"platformName\": \"LINUX\", \"acceptSslCerts\": true, \"acceptInsecureCerts\": true, \"proxy\": {\"httpProxy\": \"http://...:80\", \"proxyType\": \"manual\", \"noProxy\": \"172.*;*.local\"}, \"moz:firefoxOptions\": {\"binary\": \"/usr/local/firefox/firefox-bin\"}}"
log-level = "trace"
webdriver-executable = "/usr/local/bin/geckodriver"
session-timeout = 30

重要的是，我必须指定“noProxy”字段来插入异常列表。无论如何，每次我尝试远程启动测试时，它都会卡住，因为远程Web驱动程序似乎无法与selenium grid通信。
selenium-server的完整日志如下：

最后一个错误是浏览器没有正确配置。错在哪里？先谢谢你了。

如果你使用的是WebDriver Sampler，你不需要自己启动Firefox示例，Firefox Driver Config会处理它。也可以在此处指定代理设置：

另请注意：

通常不建议使用Selenium和WebDriver进行性能测试。不是因为它没有能力，而是因为它没有为工作进行优化，你不太可能得到好的结果。

注意：本项目无意替换JMeter中包含的HTTP采样器。相反，它是为了通过测量最终用户加载时间来补充它们。
因此，我建议考虑使用configuring JMeter to behave like a real browser并使用HTTP请求采样器。您将使用更少的资源产生相同的网络足迹。
