Episerver Find - Unable to deserialize IList<string>
Hi,
What happens if you change the type from an interface to a concrete implementation of list?
IList<string> ---> List<string>

This topic was created over six months ago and has been resolved. If you have a similar question, please create a new topic and refer to this one.
I am indexing pages which have a base class with an IList<string> property like below:
public virtual IList<string> TagCodes
{
get { return new List<string> { "Shoulder", "Knee", "Video" }; }
}
It gets indexed correctly and looks as following when I do index view:
"TagCodes": [ "Shoulder", "Knee", "Video" ],
However, when I perform the actual search I am getting the following exception "To deserialize objects the $type property must be set.". I am a bit at loss at what is happening and what I am missing.
_searchClient
.Search<ExpertBaseResourcePageType>()
.Select(p => new SearchResultItem
{
TagCodes = p.TagCodes
} as ISearchResultItem)
.GetResult();
Below is exception stack trace as well:
