I am trying to upgrade an inherited solution from v6 to v7, so far so good but I need to upgrade some legacy MNTP data and was attempting to use Phoenix Convertors but have run into the following exception:
{"Message":"An error has occurred.","ExceptionMessage":"Value cannot
be null.\r\nParameter name:
umbracoContext","ExceptionType":"System.ArgumentNullException","StackTrace":"
at Umbraco.Web.WebApi.UmbracoApiController..ctor(UmbracoContext
umbracoContext)\r\n at
Umbraco.Web.WebApi.UmbracoAuthorizedApiController..ctor()\r\n at
PhoenixConverters.Controllers.PhoenixApiController..ctor()\r\n at
lambda_method(Closure )\r\n at
System.Web.Http.Dispatcher.DefaultHttpControllerActivator.Create(HttpRequestMessage
request, HttpControllerDescriptor controllerDescriptor, Type
controllerType)"}
The solution uses the AutoFac IoC framework and the following initializes the IoC container as per the docs:
// Register umbraco context, mvc controllers and api controllers
_builder.Register(c => UmbracoContext.Current).AsSelf();
_builder.RegisterControllers(Assembly.GetExecutingAssembly());
_builder.RegisterApiControllers(typeof(UmbracoApplication).Assembly);
_builder.RegisterApiControllers(typeof(PhoenixTreeController).Assembly);
I can see that UmbracoContext is null (if I am correct) but not sure why or how to rectify. The rest of the back office appears to work fine and the initial tree loads I just get the exception when selecting one of the PhoenixConvertors child nodes in the developer section.
var resolver = new AutofacWebApiDependencyResolver(container);
GlobalConfiguration.Configuration.DependencyResolver = resolver;
But I now get the following exception but not sure where it's being thrown:
Failed to retrieve target datatypes from API

v6 > v7 Upgrade - No UmbracoContext with PhoenixConvertors

Still struggling with this but have a little progress thanks to an old thread I found here:
