<div>I upgraded the source code to .NET Core v3.1 & I'm having trouble figuring how to debug the backend issue due to lot of dependency injections, abstractions & overriding classes/methods all over. The employee who wrote this have overcomplicate
things & he had left the company so we got stuck with the confusing source code mess here that take a lot of our time & energy, to make sense of the it. :-/</div> <div> </div> <div>
The error I'm having is a 401 unauthorize response. I discovered the debugger doesnt respond in StartUp class when consuming the webservice, it only respond when you start up the Web App. So, it took us a while & finally found a hitting debugger
breakpoint on a MVC controller page to point us in the right direction. There it is saying the Identity is not authenticated so that explain the unauthorize error.</div> <div> </div> <div>
We're not familiar with this one authentication technology, `Odachi`. We believe there are 2 seperate authentication architecture, which is ehe WebApp's webpages login authorization for the customer's web browser & Odachi deal with the WebApp's webservice
login authorization for the 3rd party software making the webservice call.</div> <div> </div> <div>
Source code below is the webservice MVC controller w/ Authorization filter. Then further down will be the Startup w/ base Startup abstraction.</div> <div></div> <div>
