Return 200 and content empty

[ivanteles]

internal interface IApiService {
[Post("/v1/participante")] Task<Participante> Logar([Header("X-XSRF-TOKEN")] string xsrf, [Body] Participante model);
}

public class ApiService
{
    private static readonly HttpClient HttpClient = new(new HttpLoggingHandler()) {BaseAddress = new Uri(App.UrlApi)};
    private readonly IApiService _service = RestService.For<IApiService>(HttpClient, new RefitSettings {
        ContentSerializer = new NewtonsoftJsonContentSerializer(
            new JsonSerializerSettings {
                NullValueHandling = NullValueHandling.Ignore
            }
        )});

    public async Task<Participante> Logar(string xsrf, Participante model)
    {
        return await _service.Logar(xsrf, model);
    }
}

The call occurs without error, but the content is always returned empty.
The same endpoint communicated via httpclient returns correctly.

[ChrisPulman]

Could we get a little more information please:
Refit version, TFM, Platform.
If you have a repo demonstrating the issue this would very helpful and help us to identify the likely cause.
Thank you

Solved!

[ChrisPulman]

Out of interest was the issue something after upgrading to 7.1.0? Or a new project.

I am trying to be sure the latest release has no breaking changes, hence asking, thank you.
