Error: client_secrets.json issue when running a HTTP Azure Function

Question

I have created this HTTP trigger azure function, which contains the code(below) to upload a video to YouTube automatically. Source: (https://developers.google.com/youtube/v3/docs/videos/insert).

When I try to run the app, I am getting the following error:

Executed 'Function1' (Failed, Id=84400f0c-b6e4-4c78-bf55-30c4527a8b5f) System.Private.CoreLib: Exception while executing function: Function1. System.Private.CoreLib: Could not find file 'C:\Users\Peter\Desktop\TestDemo\UploadVideo\UploadVideo\bin\Debug\netcoreapp2.1\client_secrets.json'.

It looks like a Google Authentication error, but I am not sure how to get this fixed.

You are getting this error cause the client_secrets.json doesn't exist in the debug folder. I reproduce the error with this file default setting Copy to Output Directory, the default is Do not copy.

So just change it to Copy if newer or Copy always, the file will be in the debug folder.
