❔ Async function seems to continue running after returning.

Hi there I'm doing a post request to a REST API. I can see that the callback is running in the console when its printing the Debug.Log. So I would assume that the function would return a User that isn't null but it doesn't. I'm a bit new to asynchronous code and would love to know if I got all of this wrong and if you know a solution to my problem.

public static async Task<User> SignInAnonymous() {
  RestClient.Post<ExchangeRefreshTokenResponse>(currentRequest).Then(response => {
    Debug.Log(("IDTOKEN: " + response.id_token, "REFRESHTOKEN: " + response.refresh_token, "USERID: " + response.user_id));
    IdToken = response.id_token;
    LocalId = response.user_id;
    RefreshToken = response.refresh_token;
    RefreshTokenChanged.Invoke(RefreshToken);
    return new User("Anonymous", response.user_id, response.id_token);

  }).Catch(error => {
      Debug.Log(error.Message);
  });
  await Task.Delay(REQUEST_TIMEOUT);
  return null;
}

public static async Task<User> SignInAnonymous() {
  RestClient.Post<ExchangeRefreshTokenResponse>(currentRequest).Then(response => {
    Debug.Log(("IDTOKEN: " + response.id_token, "REFRESHTOKEN: " + response.refresh_token, "USERID: " + response.user_id));
    IdToken = response.id_token;
    LocalId = response.user_id;
    RefreshToken = response.refresh_token;
    RefreshTokenChanged.Invoke(RefreshToken);
    return new User("Anonymous", response.user_id, response.id_token);

  }).Catch(error => {
      Debug.Log(error.Message);
  });
  await Task.Delay(REQUEST_TIMEOUT);
  return null;
}

I'm not familiar with RestClient but using callbacks instead of just await here seems wrong

Thanks for responding. I'm not sure if RestClient (https://github.com/proyecto26/RestClient) supports async code then. Do you recommend a library for async web requests?:)

Ah, unity... I have not written .net framework in many many years, but I'd go for HttpClient, the one that comes with .NET by default it handles async just fine

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
