Using 7.14. I am trying to get basic information from a MNTP datatype but am getting this error when using the following code which is based on the u7 Docs. Any suggestions?

@{

    if (Model.Content.HasValue("resourcespicker"))

    {

        var docListValue = Model.Content.GetPropertyValue<string>("resourcespicker");

        var docList = docListValue.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries).Select(int.Parse);

        var docCollection = Umbraco.TypedContent(docList).Where(x => x != null);

        foreach (var item in docCollection)

        {

            <p>@item.Name</p>

        }

    }

}  

Error below:
