WebApi OAuth UseOAuthBearerAuthentication muestra el error "La secuencia contiene más de un elemento"

Question

Configuré mi WebApi OAuth 2.0 por estas líneas:

    app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions
    {
        Provider = new OAuthBearerAuthenticationProvider(),
    });

    app.UseOAuthBearerTokens(OAuthOptions);

Pero me da el siguiente error en cada solicitud:

Message : An error has occurred.
ExceptionMessage : Sequence contains more than one element
ExceptionType : System.InvalidOperationException

Mis OAuthOptions es:

    OAuthOptions = new OAuthAuthorizationServerOptions
    {
        TokenEndpointPath = new PathString("/Token"),
        Provider = new ApplicationOAuthProvider(PublicClientId, UserManagerFactory),
        AuthorizeEndpointPath = new PathString("/Account/ExternalLogin"),
        AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
        AllowInsecureHttp = true,
    };
}

Si comento UseOAuthBearerAuthentication ¡ todo está bien! No he personalizado OAuthBearerAuthenticationProvider todavía y lo uso directamente, pero ¿por qué me da error?

Answer 1

¡Debería ser un error! Utilizar

app.UseOAuthAuthorizationServer(OAuthOptions);

en lugar de

app.UseOAuthBearerTokens(OAuthOptions);
