WebAPI OAuth UseOAuthBearerAuthentication देता त्रुटि

Question

मैं इन पंक्तियों के आधार पर अपना WebAPI OAuth 2.0 कॉन्फ़िगर किया गया "अनुक्रम एक से अधिक तत्व शामिल":

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

    app.UseOAuthBearerTokens(OAuthOptions); 

लेकिन यह मुझे प्रत्येक अनुरोध पर निम्न त्रुटि देता है:

Message : An error has occurred. 
ExceptionMessage : Sequence contains more than one element 
ExceptionType : System.InvalidOperationException 
StackTrace : at System.Linq.Enumerable.SingleOrDefault[TSource](IEnumerable`1 source) 
    at Microsoft.Owin.Security.AuthenticationManager.d__8.MoveNext()

    at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() 
    at System.Web.Http.Dispatcher.HttpControllerDispatcher.d__1.MoveNext() 

मेरे OAuthOptions है:

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

अगर मैं टिप्पणी UseOAuthBearer प्रमाणीकरण सबकुछ ठीक है! मैंने अभी तक OAuthBearerAuthenticationProvider को कस्टमाइज़ नहीं किया है और मैं इसे सीधे उपयोग करता हूं लेकिन यह मुझे त्रुटि क्यों देता है?

यह एक बग होना चाहिए! का प्रयोग करें

app.UseOAuthAuthorizationServer(OAuthOptions);

बजाय

app.UseOAuthBearerTokens(OAuthOptions);
