How to add custom claims to access token in IdentityServer4? [closed]

Answer 1

Issue found.

In startup.cs instead of adding "services.AddTransient();"

Add ".AddProfileService()" to services.AddIdentityServer()

You will end up with

        services.AddIdentityServer()
            .AddTemporarySigningCredential()
            .AddInMemoryIdentityResources(Config.GetIdentityResources())
            .AddInMemoryApiResources(Config.GetApiResources())
            .AddInMemoryClients(Config.GetClients())
            .AddAspNetIdentity()
            .AddProfileService();

Thanks for Coemgen for helping out! nothing wrong with the code, just the startup was wrong.
