I've recently implemented D365 in our C# .NET Core App and it works fine on my Windows machine, and when deployed to Azure. However, one of my colleagues on Mac is running into an issue. When the ServiceClient is created, he gets the error:
Only loopback redirect uri is supported, but urn:ietf:wg:oauth:2.0:oob was found. Configure http://localhost or http://localhost:port both during app registration and when you create the PublicClientApplication object.
See below for the stack trace.
We construct the ServiceClient like this:
var connectionString = $"AuthType=ClientSecret;SkipDiscovery=true;RequireNewInstance=true;Url={settings.OrgUrl};ClientId={settings.AppClientId};ClientSecret={settings.AppClientSecret}";
this._serviceClient = new ServiceClient(connectionString);Why is it not working? Is it because he's on Mac, or is it something else?
