Cognito Authorization using ASP.Net Core
I'm trying to get my ASP.Net Core Web App to authenticate/authorize using AWS Cognito. I'm using the following example as a guideline: https://github.com/aws-samples/aws-netcore-aspnetmvc-amazon-cognito-authentication-authorization-samples
So far, I haven't been able to get the sample working and I've noticed at least one other person who has a similar issue redeeming the token.
I'm using Visual Studio 2022 and have migrated to the latest version of .Net.
When I attempt to login, I'm getting the following, any idea what might be wrong?
Thank you

Hi,
Please take a look at our documentation per endpoint. For example for the Token endpoint request [ https://docs.aws.amazon.com/cognito/latest/developerguide/token-endpoint.html ] the error means:
Client authentication failed. For example, when the client includes client_id and client_secret in the authorization header, but there's no such client with that client_id and client_secret.
There is a high chance you did not provide the Authorization header for a confidential client in the form of Basic <Base64 format of 'client_id:client_secret'

I duplicated the sample using a new ASP.Net Core MVC Web App using .Net 7.0, made the necessary changes to migrate from Program.cs + Startup.cs to just the Program.cs. I'm getting the same error.
I can zip up the solution and send if needed.
