#### Question
Am trying to implement custom token authentication with auth server . So i have used builder.Services.AddAuthenticatio in the FunctionStartUp, Am able to compile it . But while running in the local with the emulator.

When i call Http trigger functions am getting following error .

An unhandled host error has occurred.
Microsoft.AspNetCore.Authentication.Core: No authentication handler is registered for the scheme 'WebJobsAuthLevel'. The registered schemes are: BearerIdentityServerAuthenticationJwt, BearerIdentityServerAuthenticationIntrospection, Bearer. Did you forget to call AddAuthentication().Add[SomeAuthHandler]("WebJobsAuthLevel",...)?.

Can some one help me on this please ???

Does azure functions support middlewares with the latest release ?

Start by reproducing the local HTTP-trigger invocation from FunctionStartup after calling AddAuthentication(), using the reported Azure Functions v2 and .NET Core 2.2 setup. Trace how the WebJobsAuthLevel scheme is registered versus the listed custom schemes; done requires either a confirmed fix for the missing handler or clear documentation that this middleware configuration is unsupported.
