Startup Error when using JWTAuthProvider

ServiceStack Error Handling
1

Hi

I am receiving this Startup error, but not clear what I can do about it.

System.NullReferenceException: Object reference not set to an instance of an object.

It seems something with the JwtAuthProvider. I have following code in Configure:

		Plugins.Add(new AuthFeature(() => new AuthUserSession(),
			new IAuthProvider[]
			{
				new JwtAuthProviderReader
				{
					HashAlgorithm = "RS256",
#if (DEBUG)
					RequireSecureConnection = false,
#endif
					PublicKeyXml = publicKeyXml
				},
			}));

So I am only getting the JWT token in, it is provided by another microservice.

Thanks for having a look at it.

If you do not need to use ConvertSessionToTokenService and GetAccessTokenService then you can add empty ServiceRoutes dictionary to JwtAuthProviderReader initialization to avoid this exception.

Plugins.Add(new AuthFeature(() => new AuthUserSession(),
    new IAuthProvider[]
    {
        new JwtAuthProviderReader
        {
            HashAlgorithm = "RS256",
#if (DEBUG)
            RequireSecureConnection = false,
#endif
            PublicKeyXml = publicKeyXml,
            ServiceRoutes = new Dictionary<Type, string[]>()
        }
}));

If you need the services mentioned above then you shoud use JwtAuthProvider instead of JwtAuthProviderReader you’ve passed to AuthFeature constructor

Thanks! I added the empty ServiceRoutes and the startup error went away.
I don’t need JwtAuthProvider because this is hosted on another micro service.
