InvalidSessionIdException: Message: invalid session id taking screenshots in a loop using Selenium a-CodePudding

I'm coding a program with selenium in python that search a website (that changes every time but the format is similar) and download the image from it. If there's the copyright the program close the tab, otherwise it runs the rest of the program. But there's a problem: it throws an InvalidSessionIdException.

Under this there's the code I wrote and the relative error

import time

import imageio as imageio
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.support import expected_conditions as EC

PATH = Service("/Users/fscozano/documenti/chromedriver-2.exe")

print("setup")
driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()))

wait = WebDriverWait(driver, 10)

for i in range(5):
    driver.get("https://apod.nasa.gov/apod/random_apod.html")
    copyr = driver.find_elements(By.XPATH, "//center[.//b[contains(.,'Copyright')]]")
    wait.until(EC.frame_to_be_available_and_switch_to_it((By.ID, 'apod')))

    if copyr:
        driver.close()
    else:
        imageLink = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH,
        "//h1[normalize-space()='Astronomy Picture of the Day']//following::p[2]//a/img"))).get_attribute("src")
        driver.get(imageLink)

        finalImage = driver.save_screenshot("/Users/fscozano/PycharmProjects/NFT_finalProject/images/"   "HightAltitudeImage"   str(i)   ".png")
        driver.close()

The error is this

Another problem is that the program always downloads the image and don't care about the presence of "copyright"

How can I solve these problems?

CodePudding user response：

It doesn't looks like there is any dependency on the Copyright.
