    So, where you have

    dapuConfigs.CoveredLanes.ToList(),

    in your first example, try changing to:

    dapuConfigs.CoveredLanes.ElementAtOrDefault(0) == null ? "" : dapuConfigs.CoveredLanes.ElementAt(0).ToString(),
dapuConfigs.CoveredLanes.ElementAtOrDefault(1) == null ? "" : dapuConfigs.CoveredLanes.ElementAt(1).ToString(),
dapuConfigs.CoveredLanes.ElementAtOrDefault(2) == null ? "" : dapuConfigs.CoveredLanes.ElementAt(2).ToString(),
dapuConfigs.CoveredLanes.ElementAtOrDefault(3) == null ? "" : dapuConfigs.CoveredLanes.ElementAt(3).ToString(),

    Or, for matching on Id

    dapuConfigs.CoveredLanes.First(cl=>cl.Id=="").ToString(),
dapuConfigs.CoveredLanes.First(cl=>cl.Id=="").ToString(),
dapuConfigs.CoveredLanes.First(cl=>cl.Id=="").ToString(),
dapuConfigs.CoveredLanes.First(cl=>cl.Id=="").ToString(),

    or more general match on id…

    dapuConfigs.CoveredLanes.First(cl=>cl.Id.Contains("")).ToString(),
dapuConfigs.CoveredLanes.First(cl=>cl.Id.Contains("")).ToString(),
dapuConfigs.CoveredLanes.First(cl=>cl.Id.Contains("")).ToString(),
dapuConfigs.CoveredLanes.First(cl=>cl.Id.Contains("")).ToString(),

    andd adding a check for no match…

    dapuConfigs.CoveredLanes.Any(cl=>cl.Id.Contains("")) ? dapuConfigs.CoveredLanes.First (cl=>cl.Id.Contains("")).ToString() : "",
dapuConfigs.CoveredLanes.Any(cl=>cl.Id.Contains("")) ? dapuConfigs.CoveredLanes.First(cl=>cl.Id.Contains("")).ToString() : "",
dapuConfigs.CoveredLanes.Any(cl=>cl.Id.Contains("")) ? dapuConfigs.CoveredLanes.First(cl=>cl.Id.Contains("")).ToString() : "",
dapuConfigs.CoveredLanes.Any(cl=>cl.Id.Contains("")) ? dapuConfigs.CoveredLanes.First(cl=>cl.Id.Contains("")).ToString() : "",
