Getting Missing close quote error running the jmeter scripts - jmeter

Question

the below script was working fine and all of sudden the problem started and not able to identify what's the issue here is. if I replace the filepath with any thing else then it works. I have write access to that folder and able to run the test multiple times to save the files to that location. The test shows this error as soon as the scrip starts
var selenium = JavaImporter(org.openqa.selenium)
var time = JavaImporter(java.util.concurrent.TimeUnit)
WDS.browser.manage().timeouts().implicitlyWait(30, time.TimeUnit.SECONDS)
var support_ui=JavaImporter(org.openqa.selenium.support.ui)
var home = java.lang.System.getProperty('user.dir')
var io = JavaImporter(java.io)
WDS.sampleResult.sampleStart()
WDS.log.info("Load the application");
WDS.sampleResult.subSampleStart('Load the application')
WDS.browser.get('https://ea-webapp-stg-test.com/getting-started')
WDS.log.info("Enter the Credentials and click on Login");
WDS.sampleResult.subSampleStart('Enter the Credentials and click on Login')
WDS.browser.findElement(selenium.By.id("username")).sendKeys("test-user");
WDS.browser.findElement(selenium.By.id("password")).sendKeys("Testpass");
WDS.browser.findElement(selenium.By.id("ravenTermsAgree")).click();
WDS.browser.findElement(selenium.By.id("kc-login")).click();
takeScreenshot('Screenshot_Logging')
function takeScreenshot(fileName){
WDS.log.info("Taking screenshots for: "+fileName);
screenshot = WDS.browser.getScreenshotAs(selenium.OutputType.FILE)
screenshot.renameTo(new java.io.File(home + '\\Test data set\\screenshots\\'+fileName+'.png'))
}
WDS.sampleResult.sampleEnd()
The error shows as

It looks like \ character is treated as escape meta character in string, I would recommend replacing it with system independent path separator
var selenium = JavaImporter(org.openqa.selenium)
var time = JavaImporter(java.util.concurrent.TimeUnit)
WDS.browser.manage().timeouts().implicitlyWait(30, time.TimeUnit.SECONDS)
var support_ui = JavaImporter(org.openqa.selenium.support.ui)
var home = java.lang.System.getProperty('user.dir')
var io = JavaImporter(java.io)
var slash = java.io.File.separator
WDS.sampleResult.sampleStart()
WDS.log.info("Load the application");
WDS.sampleResult.subSampleStart('Load the application')
WDS.browser.get('https://ea-webapp-stg-test.com/getting-started')
WDS.log.info("Enter the Credentials and click on Login");
WDS.sampleResult.subSampleStart('Enter the Credentials and click on Login')
WDS.browser.findElement(selenium.By.id("username")).sendKeys("test-user");
WDS.browser.findElement(selenium.By.id("password")).sendKeys("Testpass");
WDS.browser.findElement(selenium.By.id("ravenTermsAgree")).click();
WDS.browser.findElement(selenium.By.id("kc-login")).click();
takeScreenshot('Screenshot_Logging')
function takeScreenshot(fileName) {
WDS.log.info("Taking screenshots for: " + fileName);
screenshot = WDS.browser.getScreenshotAs(selenium.OutputType.FILE)
screenshot.renameTo(new java.io.File(home + slash + 'Test data set' + slash + 'screenshots' + slash + fileName + '.png'))
}
WDS.sampleResult.sampleEnd()
