OrderService is always NULL in production but not in Dev. environment

Thanks man appriciate you helping me this far.

Also I may have found the solution to the original problem.

Need tot test yet so Ill let you know but It may be the dependencyregistrar.

Got this from UPS

/// <summary>
    /// Dependency registrar
    /// </summary>
    public class DependencyRegistrar : IDependencyRegistrar
    {
        /// <summary>
        /// Register services and interfaces
        /// </summary>
        /// <param name="builder">Container builder</param>
        /// <param name="typeFinder">Type finder</param>
        /// <param name="config">Config</param>
        public virtual void Register(ContainerBuilder builder, ITypeFinder typeFinder, NopConfig config)
        {
            builder.RegisterType<ShipStationService>().As<IShipStationService>().InstancePerLifetimeScope();
        }

        /// <summary>
        /// Order of this dependency registrar implementation
        /// </summary>
        public int Order => 2;
    }

In case anyone finds this interesting,

The solution to my problem:

OrderResponse retrieveOrder = _mollieOrderClient.GetOrderAsync(id).GetAwaiter().GetResult();

Interesting: https://stackoverflow.com/questions/17284517/is-task-result-the-same-as-getawaiter-getresult

Probably want to wrap it in a try/catch or set a timeout in case the task fails.  

Hopefully async gets much easier in version 4.4
