InvalidOperationException: Scheme already exists: Bearer
Microsoft.AspNetCore.Authentication.AuthenticationOptions.AddScheme(string name, Action<AuthenticationSchemeBuilder> configureBuilder)

DependencyResolutionException: An exception was thrown while invoking the constructor 'Void .ctor(Microsoft.Extensions.Options.IOptions`1[Microsoft.AspNetCore.Authentication.AuthenticationOptions])' on type 'AuthenticationSchemeProvider'.
Autofac.Core.Activators.Reflection.ConstructorParameterBinding.Instantiate()

DependencyResolutionException: An exception was thrown while activating Microsoft.AspNetCore.Authentication.AuthenticationSchemeProvider.

Scheme which you are trying to use is already used by our API. You need to create a new one with different name.
