Selenium webdriver 运行selenium webdriver脚本时发生Jmeter脚本错误

我已经在jmeter中为我的聊天机器人应用程序编写了以下脚本

WDS.sampleResult.sampleStart();
WDS.browser.get('http://interview.erainfotechbd.com:5003/');
WDS.sampleResult.getLatency();
WDS.log.info("chat bot opended");
var userName = WDS.browser.findElement(pkg.By.xpath('//input[@name="nickname"]'));
userName.click(); //clicks search field
userName.sendKeys(['tahashin']); //types word "blazemeter" in field//saves search field into searchField
var mobileNumber = WDS.browser.findElement(pkg.By.xpath('//input[@name="mobile"]'));
mobileNumber.click(); //clicks search field
mobileNumber.sendKeys(['01913498919']); //types word "blazemeter" in field//saves search field into searchField
var loginButton = WDS.browser.findElement(pkg.By.xpath('//button[@id="Enter"]'));
loginButton.click(); //clicks login button
var selectInterview= WDS.browser.findElement(pkg.By.xpath('//form[@id="myFormInt"]/input[1]'));
selectInterview.click();
timeouts.pageLoadTimeout(600, timeUnit.TimeUnit.SECONDS);
var returnedAnswer=WDS.browser.findElement(pkg.By.xpath('//input[@class="form-control"]')).getText();
var enterValidNumber= WDS.browser.findElement(pkg.By.xpath('//input[@class="form-control"]'));
enterValidNumber.sendKeys('01676912613'); 
var sendMessagebutton= WDS.browser.findElement(pkg.By.xpath('//button[@id="sendMessage"]'));
sendMessagebutton.click();
timeouts.pageLoadTimeout(600, timeUnit.TimeUnit.SECONDS);
WDS.sampleResult.sampleEnd();

运行脚本后，将显示以下异常：

我已正确配置chromedriver。出现此错误的可能原因是什么？为什么需要Oauth采样器？

将不适用于当前的JMeter版本，如果您需要将此采样器用于其他测试，则需要将JMeter版本降级为

如果您不需要OAuth采样器，只需从jmeter安装的“lib/ext”文件夹中删除

jmeter-plugins-OAuth-x.x.jar

，错误将在jmeter重新启动后消失
