Blazored Typeahead SearchMethod has the wrong return type

I'm trying to use blazored typeahed for my app but there seems to be a problem with the search method.

Here is my current code:

<BlazoredTypeaheadInput SearchMethod="Search"
                   @bind-Value="Value"
                   Placeholder="@Resources.SelectVehicle.SearchByLicensePlateNumber"
                   MinimumLength="3"
                   Debounce="500">

</BlazoredTypeaheadInput>


@code {
    private Vehicle _value;

    private async Task<List<Vehicle>> Search(string searchText)
    {
        var request = new SERVICES.FindVehiclesRequest()
        {
            LicensePlateNumber = searchText,
        };

        string[] ids = await VehicleService.FindVehicles(request);

        SERVICES.VehicleItem[] vehicles = await VehicleService.GetVehicles(ids.Take(5));
        List<Vehicle> result = vehicles
             .Select(Convert)
             .ToList();

        return await Task.FromResult(result);
    } 

Apparently, there's a mistake in the Search method as I get this error - 'Task> __generated__SelectVehicle.Search(string)' has the wrong return type' I've tried to return just return result; but it didn't help.

The SearchMethod Parameter on this component expects a return type of IEnumerable<T> inside a Task, so your method signature needs to be

private async Task<IEnumerable<Vehicle>> Search(string searchText)
