title: selenium.common.exceptions.InvalidArgumentException: Message: invalid argument: File not found error invoking send_keys() using Selenium
body: <p>I'm new to Selenium Automated Testing and I'm just trying to do a simple task by typing in "hi" in the text box on a web page.</p>
  
  <p>My code looks like this:</p>
  
  <pre><code>input = driver.find_element(By.XPATH, "//input[@type='file']")
  input.send_keys('hi')
  </code></pre>
  
  <p>But when I run the code I received this error:</p>
  
  <pre><code>selenium.common.exceptions.InvalidArgumentException: Message: invalid argument: File not found : hi
  </code></pre>
  
  <p>Any ideas on how to fix this?</p>
