Exception in thread “main” org.openqa.selenium.WebDriverException: Returned value cannot be converted to WebElement: {stacktrace=0 chromedriver 0x000000010e06dc49 chromedriver + 4893769

实现代码：
public void getElement(){
System.out.println(“定位元素开始------”);//打印成功
driver.findElement(By.id(“js-signin-btn”)).click();//无法定位到，导致失败
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}

driver.findElement(By.name(“email”)).sendKeys(“13269395194”);
driver.findElement(By.className(“js-loginPassword”)).sendKeys(“sz19870129zxh”);
WebElement NodeElement = driver.findElement(By.className(“rlf-autoin”));
NodeElement.findElement(By.tagName(“input”)).click();
List ButtonElement = driver.findElements(By.className(“rlf-group”));
ButtonElement.get(4).click();//登录button
driver.findElement(By.linkText(“找回密码”)).click();
driver.findElement(By.partialLinkText(“无法”)).click();
driver.findElement(By.xpath("//*[@id=“signin”]/div[3]/div[1]/span")).click();//手机短信的登录
driver.findElement(By.cssSelector("#signup-form > div.rlf-group.pr.phoneVerityBox > p.reSend.pa.active.js-phonecode-box > span")).click();
