Getting arguments[0].setAttribute is not a function error in Selenium

Question

I am using the below code to highlight the input box in a web page:

JavascriptExecutor js=(JavascriptExecutor)driver; 
WebElement username= driver.findElement(By.id("email"));  
js.executeScript("arguments[0].setAttribute('style','border: solid 2px 
red');", username);

It is giving me an error like this:

org.openqa.selenium.WebdriverException: unknown error: 
arguments[0].setAttribute is not a function

Note: The tag in the web page already has a style attribute in it.

Any reason to use JavascriptExecutor and not Java functions? — undetected Selenium

I think your syntax is wrong, you forget to add ''quotes near style and also remove ; before username

try this code:

JavascriptExecutor js=(JavascriptExecutor)driver; 
WebElement username= driver.findElement(By.id("email")); 
js.executeScript("arguments[0].setAttribute('style','border: solid 2px red')", username)

You are missing quotes, please try the following code,

JavascriptExecutor js=(JavascriptExecutor)driver; 
WebElement username= driver.findElement(By.id("email"));  
js.executeScript("arguments[0].setAttribute('style','border: solid 2px red');", username);

After adding the missing quote also getting the same error. @Murthi

alternatively, you can try arguments[0].style.border='solid 2px red';
