带behat的selenium：找不到会话的提供程序

Question

因此，我试图在docker容器中配置selenium，以便与behat一起使用，当我到达http://localhost:4444/status时，集线器的状态为未就绪：

{
  "value": {
    "ready": false,
    "message": "Selenium Grid not ready.",
    "nodes": [
      {
        "id": "f746de23-58e4-499d-85fd-9bad4f904488",
        "uri": "http:\u002f\u002f172.22.0.5:5555",
        "maxSessions": 2,
        "stereotypes": [
          {
            "capabilities": {
              "browserName": "chrome"
            },
            "count": 2
          }
        ],
        "sessions": [
        ]
      }
    ]
  }
}

当我运行测试时：

Could not open connection: Payload received from webdriver is valid but unexpected json: {
        "value": {
          "error": "session not created",
          "message": "Unable to find provider for session: Capabilities {browser: firefox, browserName: chrome, ignoreZoomSetting: false, name: Behat feature suite, tags: [509f70556c1c, PHP 7.4.9]}, Capabilities {browserName: chrome}, Capabilities {browserName: firefox}, Capabilities {}\nBuild info: version: '4.0.0-alpha-7', revision: '117b9d61c9'\nSystem info: host: '7f39dcd595c7', ip: '172.22.0.2', os.name: 'Linux', os.arch: 'amd64', os.version: '4.19.76-linuxkit', java.version: '1.8.0_265'\nDriver info: driver.version: unknown",

你知道吗？谢谢。

我让它与以前的版本一起工作，chrome Selenium/node-chrome:3.141.59-oxygen的图像。我必须更改behat.yml中的base_url作为WebServer的容器“url”。（http://nginx是我的案子）
