urllib.error.HTTPError: HTTP Error 404: Not Found

[ckkkkk]

This is the first time i am using the Google API key and the code is suppose to open up the browser when there is a new video uploaded from the channel. But am getting the http error. Did some searches and some forum actually recommended using the user agent, but no luck making it works.

Here is the code

import urllib3, json
import urllib.request
from selenium import webdriver
import time
import requests

def look_for_new_video():
    headers = {}
    headers['User-Agent'] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.88 Safari/537.36"
    api_key = "KEY_REMOVED"
    channel_id = "UCWr0mx597DnSGLFk1WfvSkQ"
    
    base_video_url = 'https://www.youtube.com/watch?v='
    base_search_url = 'https://wwww.googleapis.com/youtube/v3/search?'
    url = base_search_url + 'key={}&channelId={}&part=snippet,id&order=date&maxResults=1'.format(api_key, channel_id)
    req = urllib.request.Request(url, headers = headers)
    print (req)
#####Error starts here
    inp = urllib.request.urlopen(url)
    print (inp)
    resp = json.loads(inp)
    responese = requests.get(url)
    print (responese)
    
look_for_new_video()
    vidID = resp['items'][0]['id']['videoId']

    video_exists = False
    with open('videoid.json', 'r') as json_file:
        data = json.load(json_file)
        if data['videoId'] != vidID:
            driver = webdriver.Chrome()
            driver.get(base_video_url + vidID)
            video_exists = True

        if video_exists:
            with open('videoid.json', 'w') as json_file:
                data = {'videoId' : vidID}
                json.dump(data, json_file)

try:
    while True:
        look_for_new_video()
        time.sleep(10)
except KeyboardInterrupt:
    print ("Stop")

Here are the error messages

I did managed to find out which line caused the error but i couldn't really solve it even after surfing through the internet. So any help would be appreciated. Thanks in advance.
