How to resolve value error for a Youtube Comment and Reply Scraper function using Youtube API and Python

Am trying to create a function that uses Youtube API to fetch the comments and responses.

Please find my code below . This shows value error and doesn't work when am trying to store the data in DataFrame. I could understand that the issue is with the Reply Part but am not sure what went wrong. Any guidance or suggestions to tell me where I have gone wrong?

Update : I also noticed not all comments are getting extracted.

Thanks in Advance.

My Code :

def vid_comments():
        Username = []
        Comment = []
        Comment_Likes = []
        Comment_Date = []
        Reply_Count = []
        Reply = []
        Replied_By = []
        video_response=resource.commentThreads().list(part='snippet,replies',videoId=Video_ID).execute()
        while video_response:
            for item in video_response['items']:
                item_info = item["snippet"]
                topLevelComment = item_info["topLevelComment"]
                comment_info = topLevelComment["snippet"]
                Username.append(comment_info["authorDisplayName"])
                Comment.append(comment_info["textDisplay"])
                Comment_Likes.append(comment_info["likeCount"])
                Comment_Date.append(comment_info['publishedAt'])
                comment = item['snippet']['topLevelComment']['snippet']['textDisplay']
                replycount = item['snippet']['totalReplyCount']
                Reply_Count.append(replycount)
                if replycount>0:
                    for reply in item['replies']['comments']:
                        reply_info = reply["snippet"]
                        Reply.append(reply_info['textDisplay'])
                        Replied_By.append(reply_info['authorDisplayName'])
            if 'nextPageToken' in video_response:
                p_token = video_response['nextPageToken']
                video_response = resource.commentThreads().list(part = 'snippet,replies',videoId = Video_ID,pageToken = p_token).execute()
            else:
                break
    vid_comments()
    cmt_data = {'Comment': Comment,'Username':Username,'Comment Likes Count':Comment_Likes,'Comment Date':Comment_Date,'Reply Count':Reply_Count}
    Comment_Section=pd.DataFrame(cmt_data) 
    reply_data = {'Reply':Reply,'Replied_By':Replied_By}
    Reply_Section = pd.DataFrame(reply_data)  

This issues is solved with few modifications in the code
