I'm starting web scraping with python and playwright. but when I run the code I get an error .how to find type of response data(binary,text.ASCI,...) and handle the error about convert and save data as text data in a file.

from playwright.sync_api import sync_playwright
import json

def handle_response(response):
with open("copy.txt", "w", encoding="utf-8") as file:
file.write(response.text())



def main():
playwright=sync_playwright().start()
browser=playwright.chromium.launch(headless=True)
browser.new_context(no_viewport=True)
page=browser.new_page()
page.on('response',lambda response:handle_response(response))
page.goto("https://www.booking.com/hotel/it/hotelnordroma.en-gb.html?aid=304142&checkin=2025-05-15&checkout=2025-05-16#map_opened-map_trigger_header_pin")
page.wait_for_timeout(1000)
browser.close()
playwright.stop()

if __name__=='__main__':
main()
