The JSON value could not be converted to Model Blazor

Question

First Blazor WASM app. I get an error while fetching data from Server:

System.Text.Json.JsonException: Deserialization failed for one of these reasons:

1. Invalid property 'result' found within a JSON object that must only contain metadata >properties and the nested JSON array to be preserved.
2. The JSON value could not be converted to WeatherBA.Shared.Dtos.ForecastReadDto[]. Path: >$.result | LineNumber: 0 | BytePositionInLine: 10.

FetchData.razor

@code {
private ForecastReadDto[]? forecasts;

protected override async Task OnInitializedAsync()
{
    forecasts = await Http.GetFromJsonAsync<ForecastReadDto[]>("api/Forecast");
}

ForecastController.cs

public class ForecastController : ControllerBase
{
    private readonly IMediator _mediator;
    public ForecastController(IMediator mediator)
    {
        _mediator = mediator;
    }

    [HttpGet]
    public ActionResult<IEnumerable<ForecastReadDto>> GetAllForecasts()
    {
        var request = new GetAllForecastsQuery();
        var result = _mediator.Send(request);
        return Ok(result);
    }
}

GetAllForecastsQueryHandler.cs

...
public async Task<List<ForecastReadDto>> Handle(GetAllForecastsQuery request, 
CancellationToken cancellationToken)
{
    var forecasts = await _repo.GetAllAsync();
    var forecastsOrdered = forecasts.OrderBy(x => x.Date);

    return _mapper.Map<List<ForecastReadDto>>(forecasts);
}

SqlForecastRepo.cs

...
public Task<List<Forecast>> GetAllAsync()
{
    return Task.FromResult(_context.Forecasts.ToList());
}

ForecastReadDto.cs

namespace WeatherBA.Shared.Dtos;
public class ForecastReadDto
{
    public int Id { get; set; }
    public DateTime Date { get; set; }
    public int TemperatureC { get; set; }
    public string? Summary { get; set; }
}

An API Endpoint returns:

"result": [
{
  "id": 3,
  "date": "2022-01-01T00:00:00",
  "temperatureC": 20,
  "summary": "Sunny"
}
],
