NSwag Gen 14.0.2 - FromQuery not serializing properly

[gogo199432]

I'm trying to send a complex object to my GET Endpoint, however when I let it generate the client, it seems to try to send the name of the object?

The DTO:

public class FilterByMetadataDto
 {
     public string? Title { get; set; }
     public DateTime? PublishedAt { get; set; }
     public IEnumerable<string>? AuthorIds { get; set; }
     public IEnumerable<Guid>? TagGuids { get; set; }
     public bool? IsComplete { get; set; }

     [JsonIgnore]
     public bool IsEmpty => Title == null && PublishedAt == null && AuthorIds == null && TagGuids == null && IsComplete == null;

     public static bool TryParse(string? input, out FilterByMetadataDto result)
     {
       // Implemented TryParse. Not pasting it for brevity
     }
}

My Endpoint:

var bookApi = app.MapGroup("/book").WithTags("Book");
bookApi.MapGet("/{page:int}", GetBooks).WithOpenApi();
....
private static async Task<Results<Ok<IEnumerable<ReturnBookDto>>, BadRequest>> GetBooks(IBookService bookService, [FromQuery] FilterByMetadataDto? filter, int page,CancellationToken cancellationToken)
{
    return await bookService.GetBooks(page,filter,cancellationToken) is var response
        ? TypedResults.Ok(response)
        : TypedResults.BadRequest();
}

The urlBuilder in the generated C# Client:

urlBuilder_.Append("book/");
urlBuilder_.Append(System.Uri.EscapeDataString(ConvertToString(page, System.Globalization.CultureInfo.InvariantCulture)));
urlBuilder_.Append('?');
if (filter != null)
{
    urlBuilder_.Append(System.Uri.EscapeDataString("filter")).Append('=').Append(System.Uri.EscapeDataString(ConvertToString(filter, System.Globalization.CultureInfo.InvariantCulture))).Append('&');
}
urlBuilder_.Length--;

  }
}

On a related note the swagger ui seems to behave slightly differently. There I can input the properties of the DTO object as expected, however when it sends it, there is no identifier after the ? in the curl statement. But if I add an extra "filter=" AspNet seems to recognize that this should be parsed.

(I'm using AspNetCore 8.0.1)

Is this still teething issue with the 14.0 Release? Or am I doing something wrong?
