'getting Invalid session id when trying to close the webdriver browser

In Jmeter webdriver sampler when I try to close the browser with the below code I am getting an invalid session id and my test gets failed. This error is gone when I comment out that browser.close() line. But I want to make sure the browser is closed after my test is done so it can give some space in the RAM.

At the very end of the test I am calling this logout script

var selenium = org.openqa.selenium
var support_ui=JavaImporter(org.openqa.selenium.support.ui) 
var EC = org.openqa.selenium.support.ui.ExpectedConditions

WDS.sampleResult.sampleStart()
-- some code
logout()
WDS.sampleResult.sampleEnd()

function logout(){
    var logoutBtn = waitByElement(selenium.By.cssSelector("button[title='User Options']"), EC.elementToBeClickable, 30)
    logoutBtn.click();
    WDS.browser.findElement(selenium.By.cssSelector("button[data-testid='logout']")).click();
    var userNameField = waitByElement(selenium.By.xpath("//*[contains(text(),'Disclaimer')]"), EC.presenceOfElementLocated, 60)
    takeScreenshot('screenshot_loggedout')
    WDS.browser.close()
}

Error in the console.

Just remove WDS.browser.close() statement, the WebDriver instance is getting closed automatically when the thread is being ended, there is no need to close/exit the browser.
