硒找到了元素，但由于缺少元素ID而无法与它进行交互

Question

所以我有一个运行良好的代码，直到今天我正在处理脚本的其他部分，并且突然有一部分停止工作，我的代码是：

$host = 'http://host.com:4444/wd/hub';
$caps= DesiredCapabilities::chrome();
$options = new ChromeOptions();
$options->addArguments(['--headless','--no-sandbox', '--window-size=1000,1000']);
$caps->setCapability(ChromeOptions::CAPABILITY, $options);
$driver = RemoteWebDriver::create($host, $caps, 5000);

$driver->manage()->deleteAllCookies();

echo "[".date("r")."]"."---- LOGIN PROCESS ---- \n";

$driver->get("https://www.example.com/login/");

$driver->wait(10)->until(
    WebDriverExpectedCondition::presenceOfAllElementsLocatedBy(
        WebDriverBy::name('password')
    )
);
$driver->takeScreenshot('image.png');
$driver->findElement(WebDriverBy::name('username'))->click();

该元素是一个文本字段，向其发送键会产生相同的异常，即：

Fatal error: Uncaught Facebook\WebDriver\Exception\UnknownCommandException: POST /session/330d05c02583a90a227cddf8c9db000a/element//click

但是，如果我只是寻找元素并转储返回值，那并不是说找不到它：

有人知道我在做什么错吗？它不在iframe中，它存在，没有对话框，什么也没有。.请注意，在单击错误中，没有元素ID：POST / session / 330d05c02583a90a227cddf8c9db000a / element // click

但是就库而言，我没有做任何更改吗？

问题似乎出在库中，不知道发生了什么，但是运行composer remove并要求再次解决它。
