I can’t seem to solve this one. All other questions i can find with the same issue are for Newtonsoft.Json.

I use an external provided json API which returns a dictionary. But if it’s empty, they return an empty array:

With data:

"booking/index": {
   "key": {
         data...
          }
}

Without data:

"booking/index": []

So the System.json deserializer fails with this error (which is understandable):

System.Text.Json.JsonException: The JSON value could not be converted to System.Collections.Generic.Dictionary`2[System.String,checkfront_reports.Models.Api.BookingIndexIndexObj]. Path: $[‘booking/index’] | LineNumber: 0 | BytePositionInLine: 408.

For reference here is the call i make and the data model:

var bookingIndex = await httpClient.GetFromJsonAsync<BookingIndexObj>($"booking/index?start_date={startDate.ToString("yyyy-MM-dd")}&end_date={endDate.ToString("yyyy-MM-dd")}");

public class BookingIndexObj
{
    public BookingRequestObj Request { get; set; }

    [JsonPropertyName("booking/index")]
    public Dictionary<string, BookingIndexIndexObj> BookingIndex { get; set; }
}

public class BookingIndexIndexObj
{
    public string? Code { get; set; }

    [JsonPropertyName("status_id")]
    public string? StatusId { get; set; }
}

public class BookingRequestObj
{
    public int Page { get; set; }

    public int Pages { get; set; }
}
