How to implement, YoutubeAPI Upload code written in C#, to upload videos to YouTube?

[Milesleam]

I am creating an Azure function, and this function will upload a video to my YouTube channel when there is new video in my 'video' container. I am using the sample YouTubeAPI upload code that was provided: Videos: insert | YouTube Data API | Google Developers . The problem I am having is that, when I run my function it compiles fine(I have shared the console output below), but videos are not getting uploaded to my YouTube channel. I am not sure if I am missing anything else in the code, if it is an authentication issue or if it needs to re-factored? Could you please have a look at code? It would be great, if I could use an Azure function to upload videos to Youtube.
Here is the code, along with other files:

Function1.cs:

using System;
using System.IO;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;

using Google.Apis.Upload;
using Google.Apis.YouTube.v3.Data;
using System.Reflection;
using Google.Apis.YouTube.v3;
using Google.Apis.Services;
using System.Threading;

namespace YoutubeUploadFunction
{
public static class Function1
{
[FunctionName("Function1")]
public static async Task Run([BlobTrigger("video/{name}", Connection = "AzureWebJobsStorage")]Stream myBlob, string name, Microsoft.Azure.WebJobs.ExecutionContext context, ILogger log)
{
UserCredential credential;
using (var stream = new FileStream(System.IO.Path.Combine(context.FunctionDirectory, "client_secrets.json"), FileMode.Open, FileAccess.Read))
{
credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
GoogleClientSecrets.Load(stream).Secrets,
new[] { YouTubeService.Scope.YoutubeUpload },
"user",
CancellationToken.None
);
}

var youtubeService = new YouTubeService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = Assembly.GetExecutingAssembly().GetName().Name
});

var video = new Video();
video.Snippet = new VideoSnippet();
video.Snippet.Title = "Default Video Title";
video.Snippet.Description = "Default Video Description";
video.Snippet.Tags = new string[] { "tag1", "tag2" };
video.Snippet.CategoryId = "22";
video.Status = new VideoStatus();
video.Status.PrivacyStatus = "unlisted";
var VideoInsertRequest = youtubeService.Videos.Insert(video, "snippet,status", myBlob, "video/*");
await VideoInsertRequest.UploadAsync();
}
}
}

client_secrets.json:

{
"installed": {
"client_id": "147300761218-dl0rhktkoj8arh0ebu5pu56es06hje5p.apps.googleusercontent.com",

"client_secret": "xxxxxxxxxxxxxxxxxx",
"redirect_uris": [ "urn:ietf:wgauth:2.0ob"]
}
}

Local.Setting.Json:

{
"IsEncrypted": false,
"Values": {
"AzureWebJobsStorage": "DefaultEndpointsProtocol=https;AccountName=uploadvideotoyoutube;AccountKey=xxxxxxxxxxxxxxxxxxxxxx==;EndpointSuffix=core.windows.net",
"FUNCTIONS_WORKER_RUNTIME": "dotnet"
}
}

This is the console output:
