I need some guidance on I'm working on a project and hit a roadblock. I'm currently working with an scenario with Selenium WebDriver when trying to automate a file upload in a React application using Firefox. The file input is wrapped in a custom React component, and when I attempt to send the file path to the input, it throws a 'ElementNotInteractableException'. I've tried using the standard method to locate the input element and send the file path, but it doesn't seem to interact as expected. Here's the code snippet I'm using: ```python 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 # Initialize WebDriver browser = webdriver.Firefox() browser.get('http://example.com/upload') # Wait for the input to be present wait = WebDriverWait(browser, 10) file_input = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, '.custom-file-input'))) # Attempt to send the file path file_input.send_keys('/path/to/your/file.txt') ``` Despite the presence of the input, the exception suggests that the element is not interactable. I also tried switching to a different locator strategy and even added explicit waits, but the same scenario continues. Interestingly, when I run the test in Chrome, it works perfectly, leading me to suspect that the scenario is specific to Firefox. I have confirmed that the file input is indeed visible and not disabled. I'm using Selenium 4.0.0 and Firefox 93.0. Any insights or workarounds would be greatly appreciated! I'm using Python 3.10 in this project. Thanks in advance!
