It's been suggested by the developers of scrapy_playwright to instantiate the DOWNLOAD_HANDLERS and TWISTER_REACTOR into your script.

A similar comment is provided here

Here's a working script implementing just this:

import scrapy
from scrapy_playwright.page import PageCoroutine
from scrapy.crawler import CrawlerProcess

class ProductSpider(scrapy.Spider):
    name = 'product'

    def start_requests(self):
        yield scrapy.Request(
            'https://shoppable-campaign-demo.netlify.app/#/',
            callback = self.parse,
            meta={
                'playwright': True,
                'playwright_include_page': True,
                'playwright_page_coroutines': [
                    PageCoroutine("wait_for_selector", "div#productListing"),
                ]
            }
        )

    async def parse(self, response):
        container = response.xpath("(//div[@class='col-md-6'])[1]")
        for items in container:
            yield {
                'products':items.xpath("(//h3[@class='card-title'])[1]//text()").get()
            }
        # parses content

if __name__ == "__main__":
    process = CrawlerProcess(
        settings={
            "TWISTED_REACTOR": "twisted.internet.asyncioreactor.AsyncioSelectorReactor",
            "DOWNLOAD_HANDLERS": {
                "https": "scrapy_playwright.handler.ScrapyPlaywrightDownloadHandler",
                "http": "scrapy_playwright.handler.ScrapyPlaywrightDownloadHandler",
            },
            "CONCURRENT_REQUESTS": 32,
            "FEED_URI":'Products.jl',
            "FEED_FORMAT":'jsonlines',
        }
    )
    process.crawl(ProductSpider)
    process.start()

And we get the following output:

{'products': 'Oxford Loafers'}

You can use waitForFunction:

month = page.querySelector(".day__month_btn").innerText()
page.waitForFunction("document.querySelector('.day__month_btn').innerText() !== '" + month + "'")

https://stackoverflow.com/questions/64569685/using-playwright-for-python-how-can-i-wait-for-a-field-selector-result-to-cha

This should get you started, because you don't really need to do fancy image trickery.

All reddit posts have data-testid=post-container selectors which let you get the top level post. All comments have a .Comment class you can use, so you can enumerate all the comments on any given reddit post and capture them separately if that's what you want.

Some major caveats of this code:

It does not respect comment nesting - I only took a brief glance at Reddit's page source but they don't seem to have easy ways of getting comment chains.
Reddit could change their selector names/CSS classes any time, and they do have some inconsistencies in how they seem to name things anyway.
You specify you want to capture AskReddit threads, which can be quite large, so you could easily end up with, say, 1000+ comment screenshots on popular threads, or even 10K+ screenshots if you just let it run with abandon. I set a limit of 10, modify code as needed.
I wrote this as a demonstration, I have no idea how it will perform on giant posts or such, but hopefully it shows you how to actually pull the information you want. If you need to do more work, you will likely have to inspect Reddit page layouts with your browser's developer tools.

#!/usr/bin/env python3

import asyncio
from playwright.async_api import async_playwright, Browser

MAX_COMMENT_LIMIT = 10


async def capture(browser: Browser,  url: str) -> None:
    page = await browser.new_page()

    await page.goto(url)
    posts = page.locator("data-testid=post-container")

    # reddit loads differently sometimes, so you need to
    # find the first post on the page
    await posts.first.screenshot(path="post.png")

    # this does not respect comment-nesting
    comments = page.locator(".Comment")
    count = await comments.count()
    print(f"Found {count} comments")
      
    for i in range(count):
        await comments.nth(i).screenshot(path=f"comment-{i}.png")

        if i+1 == MAX_COMMENT_LIMIT:
            print(f"Screened {MAX_COMMENT_LIMIT} images, stopping.")
            break


async def main() -> None:
    reddit_url = "https://www.reddit.com/r/cpp/comments/w9xkmf/c_for_scientific_programming/"
    async with async_playwright() as p:
        browser = await p.chromium.launch()
        await capture(browser, reddit_url)
        await browser.close()

asyncio.run(main())

You can use a factory function here to pass the page, and the global_variable. Keep in mind that navigating away from the page from inside the callable will lead to an error. So make sure whatever you are clicking does not change the current URL of the page.

def wrapper(page, global_variable):
    def test(event):
        page.locator('//*[@id="n-currentevents"]/a').click()  # Action before boolean
        if event.url == 'https://en.wikipedia.org/':
            return True
    return test

Then, you can register the above function using page.wait_for_event like this:

page.wait_for_event('request', wrapper(page, global_variable))

Remember: You need to pass functions/callables (not their return values) to page.wait_for_event

https://stackoverflow.com/questions/73093763/playwright-page-wait-for-event-function-how-to-access-the-page-and-other-variabl

You can define your own function like this one:

def my_own_wait_for_selector(page, selector, time_out):
    try:
        page.wait_for_selector(selector, timeout=time_out)
        return True
    except:
        return False

That function will wait for a selector and if given some time (miliseconds) the element is not there it will return False instead of trowing an error.

Then in your code you could try something like:

while not my_own_wait_for_selector(page, "my_button_selector", 5000):
    page.reload()
page.locator("my_button_selector").click()

As you can see we are checking if our button is present, and we will wait only 5 seconds, if after 5 seconds the button is not there, we will reload, and again and again until our button is there, once our button is there code will continue and then we will click the button.

Be careful, because if your button is never there, your script will reload and your script will never finish, so you should add some other condition to your while

https://stackoverflow.com/questions/74391065/python-playwright-make-code-reload-page-after-timeout-until-it-finds-the-object

You can try the next example playwright with bs4.

Code:

from playwright.sync_api import sync_playwright
from bs4 import BeautifulSoup

data = []
with sync_playwright() as p:
    browser = p.chromium.launch(headless=False)
    context = browser.new_context(viewport={"width": 1920, "height": 1080})
    page = context.new_page()
    page.goto('https://workspace.google.com/marketplace/search/word')
    page.wait_for_timeout(4000)

    soup = BeautifulSoup(page.content(), 'lxml')
    for card in soup.select('a.RwHvCd'):
        link = 'https://workspace.google.com' + card.get('href').replace('./', '/') 
        print(link)

You didn't set the cookie properly. You have

  # 1. Set the fields of the cookie.
  #    Give the cookie a value from the 'yourname' variable,
  #    a domain (localhost), and a max-age.
  c['value'] = yourname
  c['domain'] = 'localhost'
  c['max_age'] = 60

and the solution is

  c['yourname'] = yourname
  c['yourname']['domain'] = 'localhost'
  c['yourname']['max-age'] = 60

I have the same problem. As David said, this error means that python-playwright or selenium is not launching correctly. What I did is

Check the version of your chrome Right upper corner -> help -> About Google Chrome
Download the chromedriver from chromedriver!
let your API find the driver

api = TikTokApi.get_instance(use_selenium=True, executablePath="/path/to/chromedriver")
