[Skype] Can't download an attachment which a user sends to the bot.

Version

SDK 4.5.2

Description

I’m trying to download a video message the user sent to the bot and I get 500 without any error message. It happens when I call GetByteArrayAsync but GetTokenAsync works just fine and returns the token. On the other hand it works fine when I send a video file as a file attachment. Please let me know if you have any ideas on how to fix this.

I get 500 when I try to download this file for example: https://smba.trafficmanager.net/apis/v3/attachments/0-weu-d11-a7dd2f30f52f28e7c657bbffc81be9e5/views/original

public async Task<byte[]> LoadAttachmentAsBytes(Attachment att, string serviceUrl)
{
    var credentials = new MicrosoftAppCredentials("appId", "password");
    using (var connectorClient = new ConnectorClient(new Uri(serviceUrl), credentials))
    {
        var token = await credentials.GetTokenAsync();

        var uri = new Uri(att.ContentUrl);
        using (var httpClient = new HttpClient())
        {
            httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
            httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/octet-stream"));

            return await httpClient.GetByteArrayAsync(uri);
        }
    }
}

@dmvtech It reproduces when I send a video message in skype. Looks like I’m not only one who is facing this problem https://social.msdn.microsoft.com/Forums/officeocs/en-US/cf97950f-7af6-4ed4-a053-d3453198c090/500-server-error-while-downloadning-file-from-skype?forum=AzureCognitiveService
