I'm having an issue when I'm going to send data in text field. I got an exception.
I'm using Firefox version 54.0b1 (32-bit) and Selenium 3.3.1.
driver.findElement(By.xpath(".//*[@id='email']")).sendKeys("Test");
The exception:
Exception in thread "main" org.openqa.selenium.InvalidArgumentException: Expected [object Undefined] undefined to be a string
