Selenium web驱动程序:选择器无效：*:-webkit-full-screen-ancestor

Question

所以下面的代码以前是可以工作的，但是现在我运行它，它总是给我这个异常。该代码主要用于在youtube的搜索栏中输入内容，然后单击搜索按钮。

代码：

WebDriver driver = new HtmlUnitDriver();
driver.get("https://www.youtube.com");
driver.findElement(By.name("search_query")).sendKeys("Selenium WebDriver"+Keys.ENTER);
driver.findElement(By.id("search-btn")).click();
List<WebElement> links = driver.findElements(By.tagName("a"));
for (int i = 0; i < links.size(); i++) {
    // print the link text
    System.out.println(links.get(i).getAttribute("title"));
    // Print the href's
    System.out.println(links.get(i).getAttribute("href"));
}    

该栏的html为：

< input id="masthead-search-term" autocomplete="off" autofocus="" onkeydown="if (!this.value &amp;&amp; (event.keyCode == 40 || event.keyCode == 32 || event.keyCode == 34)) {this.onkeydown = null; this.blur();}" class="search-term masthead-search-renderer-input yt-uix-form-input-bidi" name="search_query" value="" type="text" tabindex="1" placeholder="" title="Search" dir="ltr" spellcheck="false" style="outline: none;">

搜索按钮的html为：

<button class="yt-uix-button yt-uix-button-size-default yt-uix-button-default search-btn-component search-button" type="submit" onclick="if (document.getElementById('masthead-search-term').value == '') return false; document.getElementById('masthead-search').submit(); return false;;return true;" id="search-btn" tabindex="2" dir="ltr"><span class="yt-uix-button-content">Search</span></button>

我试着用javascript打开和关闭它，但给了我同样的异常。我尝试使用xpath，但给了我同样的异常。

异常跟踪：

在所提供的示例中，第39行是第3行。如果有遗漏或误导，我深表歉意。这是第一次使用stackoverflow。如果有任何答案，我都会很高兴。

无法使用Keys.ENTER。这是更正后的代码-：

WebDriver driver = new HtmlUnitDriver();
driver.findElement(By.name("search_query")).sendKeys("Selenium WebDriver");
driver.findElement(By.id("search-btn")).click();
List<WebElement> links = driver.findElements(By.tagName("a"));
for (int i = 0; i < links.size(); i++) {
 // print the link text
System.out.println(links.get(i).getAttribute("title"));
// Print the href's
System.out.println(links.get(i).getAttribute("href"));
}
