AddFaceFromStreamWithHttpMessagesAsync(personGroupId, personId, stream) failing, image size is too small

The Http Header Content-Length is always equal to 0, that’s why the call is failing with a stream and the response message equals “Image size is too small”, here is a solution I have found to solve this issue, I hope it helps, if you find or already have a better solution, tell us. Have a nice day :

public async Task<bool> AddFace(string personGroupId, Guid personId, Stream image)
{
    HttpClient client = faceClient.HttpClient;
    
    string uri = faceClient.Endpoint + "/face/v1.0/persongroups/"+ personGroupId +"/persons/"+ personId + "/persistedFaces";

    HttpResponseMessage response;
    image.Position = 0;

    using (StreamContent content = new StreamContent(image))
    {
        content.Headers.Add("Ocp-Apim-Subscription-Key", new List<string>(){"<Subscriptionkey>"});
        content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
        content.Headers.ContentLength = image.Length;
        
        try
        {
            // Execute the REST API call.
            response = await client.PostAsync(uri, content);
            // Get the JSON response.
            string contentString = await response.Content.ReadAsStringAsync();

            var obj = JsonConvert.DeserializeObject<PersistedFace>(contentString);

            if(response.IsSuccessStatusCode && !obj.PersistedFaceId.Equals(Guid.Empty))
            {
                return true;
            }
        }
        catch(Exception ex)
        {
            Debug.WriteLine(ex.Message);
        }

        return false;
    }
}
