Once you open WhatsApp Web and enter the chat and try to locate the element with CSSSELECTOR:

input[type='file']

The default element is identified which is:

Though an element with style="display: none; but accepts only image/*. Hence when you pass a PDF file you see the error:

1 file you tried to add is not supported.

Solution

You need to send the PDF file to the following element:

and this element would accept all the supported files including PDF.

Working code block:

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expectedconditions as EC
driver.get(url='https://web.whatsapp.com/')

... code to open WhatsApp Web and enter the chat ...

WebDriverWait(driver, 20).until(EC.elementtobeclickable((By.XPATH, "//div[@aria-label='Search input textbox']/p"))).sendkeys("Paullyno")
WebDriverWait(driver, 20).until(EC.elementtobeclickable((By.XPATH, "//span[contains(., 'Chats')]//following::span[starts-with(@title, 'Paullyno')]"))).click()
WebDriverWait(driver, 20).until(EC.elementtobeclickable((By.XPATH, "//span[@data-icon='plus-rounded']"))).click()
WebDriverWait(driver, 20).until(EC.elementtobeclickable((By.XPATH, "//div[@role='application']/ul//span[text()='Document']"))).click()
attach = driver.findelement(By.CSSSELECTOR, "input[type='file'][multiple]")
attach.sendkeys(os.path.abspath(default/archive.pdf))
WebDriverWait(driver, 20).until(EC.elementtobe_clickable((By.XPATH, "//div[@aria-label='Send']/span[@data-icon='wds-ic-send-filled']"))).click()

I apologize if there are any errors in the English; I'm using Google Translate. For some reason, Chrome only loads the input now when the attach button is clicked. I tried every way to make it attach to the correct input, but it always went to the same incorrect one. So what worked for me was the following: I got to a point where I was out of patience and trying everything I could with Gemini to solve it. There's definitely room for improvement in this part of the code, but I believe the logic for correction is the same. I didn't write any of this code, so I don't recommend copying and pasting. I kindly ask that if anyone has a cleaner solution without using AI, please reply here.
