I have tried the method from this page: Upload file with Selenium in Python

Code:

file_button = browser.find_element_by_id('fileUploadProxy')
file_button.send_keys('/Users/home/Downloads/1-Students-and-Parent-Email.csv')

But I get the following error:

Traceback (most recent call last):
  File "test.py", line 110, in <module>
    upload_students_results('Surname, Name')
  File "test.py", line 91, in upload_students_results
    file_button.send_keys('/Users/home/Downloads/1-Students-and-Parent-Email.csv')

The problem is - you are sending keys to the div element which is not "interactable", does not accept the keys - hence the "cannot focus element" error.

The idea behind the solution you've linked is to send keys to the input element with type="file" that is responsible for the file upload. Find this element in your HTML and send keys to it.

Note that this element could be invisible. In this case, you should first make it visible for the send_keys() to work.

Update:

Okay, now we at least know which element is our desired one:

<input type="file" name="fileToUpload" id="fileToUpload2" class="fileToUpload">

Since you have troubles locating this element, either try waiting for it:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC


file_upload = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.ID, "fileToUpload2"))
)
file_upload.send_keys('/Users/home/Downloads/1-Students-and-Parent-Email.csv')

Or/and, check if this element is inside an iframe - if it is, you would need to switch into the context of the iframe and only then perform the element search.

  • I think I found it `` so I changed the code to > `file_button = browser.find_element_by_id('fileToUpload2')` but it is still throwing an error? Also tried adding .click() too. – Phil May 04 '17 at 07:14
  • @Phil which error is thrown now? Is the element visible/editable? – alecxe May 04 '17 at 07:16

  • Thank you, it worked for me. and it also was in iframe. So I switch to by `driver.switch_to.frame(browser.find_element_by_name('frame_element'))` – Mr.Takeo Feb 05 '19 at 02:41

I had the same problem when I inserted the file path as a string. This is functional:file_input.send_keys(os.path.abspath("path/to/the/file.xyz"))
