Master and Detail must be set before adding MasterDetailPage to a container

We have made no changes to our code but updating the newest (stable) Xamarin.Forms v2.1.0.6529 and FreshMVVM (1.0.3.003) we are now receiving this error:

Master and Detail must be set before adding MasterDetailPage to a container

I can confirm that Detail is not being set as the resolver can’t find the PageModels.

I had a similar problem on another project and it all resolved itself by adding a Title to the Master ContentPage, vis-a-vis:

  <MasterDetailPage.Master>
    <ContentPage Title="My Title" />
  </MasterDetailPage.Master>
  <MasterDetailPage.Detail>
    <NavigationPage>
      <x:Arguments>
        <ContentPage />
      </x:Arguments>
    </NavigationPage>
  </MasterDetailPage.Detail>

Hi ! I solved the problem because the Content Page need to have a title :

<MasterDetailPage.Detail>

<NavigationPage>
  <x:Arguments>
    <ContentPage Title="This is a view"></ContentPage>
  </x:Arguments>
</NavigationPage>

</MasterDetailPage.Detail>
