Custom Claims are not being accessed in client with identityserver 4 .Net core 2.0

I have following in my client startup.cs.

services.AddAuthentication(options => { options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme; options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme; }) .AddCookie() .AddOpenIdConnect(options => { options.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme; // cookie middle setup above options.Authority = AuthSetting["Authority"]; // Auth Server options.RequireHttpsMetadata = false; // only for development options.ClientId = AuthSetting["ClientId"]; // client setup in Auth Server options.ClientSecret = AuthSetting["ClientSecret"]; options.ResponseType = "code id_token"; // means Hybrid flow (id + access token) options.GetClaimsFromUserInfoEndpoint = true; options.SaveTokens = true; //options.ClaimActions.MapJsonKey(ClaimTypes.Email, "email", ClaimValueTypes.Email); //options.ClaimActions.Clear(); //https://stackoverflow.com/a/47896180/9263418 //options.ClaimActions.MapUniqueJsonKey("Aes", "Aes"); //options.ClaimActions.MapUniqueJsonKey("foo", "foo"); //options.ClaimActions.MapJsonKey("Aes", "Aes"); //https://github.com/aspnet-contrib/AspNet.Security.OAuth.Providers/issues/210 }); 

Following is my Identityserver's startup.cs

services.AddIdentityServer(options => { options.Events.RaiseSuccessEvents = true; options.Events.RaiseFailureEvents = true; options.Events.RaiseErrorEvents = true; options.Events.RaiseInformationEvents = true; }) .AddInMemoryClients(Clients.Get()) .AddInMemoryIdentityResources(Resources.GetIdentityResources()) .AddInMemoryApiResources(Resources.GetApiResources()) .AddDeveloperSigningCredential() .AddExtensionGrantValidator<Extensions.ExtensionGrantValidator>() .AddExtensionGrantValidator<Extensions.NoSubjectExtensionGrantValidator>() .AddJwtBearerClientAuthentication() .AddAppAuthRedirectUriValidator() .AddClientConfigurationValidator<DefaultClientConfigurationValidator>() .AddProfileService<ProfileService>(); 

Following is my ProfileService.cs file.

public class ProfileService : IProfileService { public Task GetProfileDataAsync(ProfileDataRequestContext context) { // Processing var claims = new List<Claim> { new Claim("Email", "someone2gmail.com"), }; context.IssuedClaims.AddRange(claims); return Task.FromResult(0); } public Task IsActiveAsync(IsActiveContext context) { // Processing context.IsActive = true; return Task.FromResult(0); } } 

I am not able to access Mail claim in client application.

Checked many references.

But none of them are working for me. Any guess that what might be missing?
