An unknown server-side error occurred while processing the command. Original error: unknown error: cannot focus element using emulator browser

Question

I am able to click that username field but not able to pass the values in that field. Facing the below error.

driver.get("xxxx");
WebDriverWait wait = new WebDriverWait(driver, 60);
WebElement username = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("xxxx")));
username.click();
username.sendKeys("xxxxxxxx");

Error I received -

An unknown server-side error occurred while processing the command. Original error: unknown error: cannot focus element (Session info: chrome=69.0.3497.100)

Answer 1

You can use click(), clear() and sendkeys() combination, it worked for me :

username.click(); username.clear(); username.sendkeys("xxxx")

Answer 2

This error message...

An unknown server-side error occurred while processing the command. Original error: unknown error: cannot focus element (Session info: chrome=69.0.3497.100)

...implies that the Selenium was unable to focus on the desired element.

To invoke sendKeys() instead of visibilityOfElementLocated() you need to induce WebDriverWait for the elementToBeClickable() and you can use either of the following Locator Strategies:

• id:

  WebElement username = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.id("xxxx")));
  username.click();
  username.clear();
  username.sendKeys("xxxxxxxx");
  

• cssSelector:

  WebElement username = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("#xxxx")));
  username.click();
  username.clear();
  username.sendKeys("xxxxxxxx");
  

• xpath:

  WebElement username = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//*[@id='xxxx']")));
  username.click();
  username.clear();
  username.sendKeys("xxxxxxxx");
