Getting KeyError: 'viewCount' for using Youtube API in Python

I'm trying to get the view count for a list of videos from a channel. I've written a function and when I try to run it with just 'video_id', 'title'& 'published date' I get the output. However, when I want the view count or anything from statistics part of API, then it is giving a Key Error.

Here's the code:

def get_video_details(youtube, video_ids):    all_video_stats = []    for i in range(0, len(video_ids), 50):        request = youtube.videos().list(                        part='snippet,statistics',                        id = ','.join(video_ids[i:i+50]))        response = request.execute()        for video in response['items']:            video_stats = dict(                            Video_id = video['id'],                            Title = video['snippet']['title'],                            Published_date = video['snippet']['publishedAt'],                            Views = video['statistics']['viewCount'])            all_video_stats.append(video_stats)    return all_video_statsget_video_details(youtube, video_ids)

And this is the error message:

---------------------------------------------------------------------------KeyError                                  Traceback (most recent call last)~\AppData\Local\Temp/ipykernel_18748/3337790216.py in <module>----> 1 get_video_details(youtube, video_ids)~\AppData\Local\Temp/ipykernel_18748/1715852978.py in get_video_details(youtube, video_ids)     14                             Title = video['snippet']['title'],     15                             Published_date = video['snippet']['publishedAt'],---> 16                             Views = video['statistics']['viewCount'])     17      18             all_video_stats.append(video_stats)KeyError: 'viewCount'

I was referencing this Youtube video to write my code.

Thanks in advance.
