This is the error:

'Content with id '286580' is of type 'Castle.Proxies.ImageOrVideoBlockProxy' which does not inherit required type 'EPiServer.Core.PageData''

The error occurs on search.GetPagesResult();. Here's what the code looks like:

var filter = BuildFilter(searchQuery, name, state, city, lat, lng, amenities, type, eventTypes, isVenue);
var search = client.Search<ClubPage>().Filter(filter).Take(MAXRESULTS);

if (sort == "distance" && lat != null && lng != null)
{
    search = search.OrderBy(p => p.Location).DistanceFrom(GetGeoLocation(lat, lng));
}
else
{
    search = search.OrderBy(p => p.DisplayName);
}

var results = search.GetPagesResult();

I ran the Find indexing before I exported the int database for local testing. And I made sure that the find URL and index for integration was in my web.config. Any ideas what's going on here?
