The inline constraint resolver of type 'DefaultInlineConstraintResolver' was unable to resolve the following inline constraint: 'objectType'

I have an Optimizely 11.20 solution with controllers that use inline route constraints like this:

`[Route("   {market:market}/{type:objectType}/{county?}/{municipality?}/{city?}/{mainDistrict?}/{district?}/{streetAddress?}", Name = "Search02")]

public async Task Index(...`

Where the constrains are registered in Global.asax like this:

`public static void RegisterRoutes(RouteCollection routes)    {        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");        routes.IgnoreRoute("authui/{*pathInfo}");        routes.IgnoreRoute("util/{*pathInfo}");        var constraintResolver = new DefaultInlineConstraintResolver();        constraintResolver.ConstraintMap.Add("objectType", typeof(ObjectTypeConstraint));        constraintResolver.ConstraintMap.Add("market", typeof(MarketConstraint));        routes.MapMvcAttributeRoutes(constraintResolver);    }`

Now I also have a third party nuget package installed: TedGustaf.Episerver.AdaptiveImage.And when that addon initializes I get this error message:

The inline constraint resolver of type 'DefaultInlineConstraintResolver' was unable to resolve the following inline constraint: 'objectType'.

How can I tell the TedGustaf.Episerver.AdaptiveImages initialization to use the DefaultInlineConstraintResolver that have registered the constraints?

I have tried to register the RouteConfig.RegisterRoutes(RouteTable.Routes); further up in the Application_Start() but that did not help.
