Request timeout. SbOpenChannel.SendFileMessage()

[Problem/Question]
Good day!
I am sending message files to a personal open channel.
From my experience, I will say this: if I send a file of less than 1 megabyte, then everything is fine. But if I send a file larger than 1 megabyte, I get a “Request timeout” warning. At the same time, the progress of sending the file goes astray and becomes 0 percent.

[SDK Version]
com.sendbird.chat
4.0.0-beta.3

[Reproduction Steps]

  1. I use the NativeGallery plugin to select a file to send and receive the string filePath response

  2. I pass the received filePath as an argument to create a new SbFileInfo, something like:

     var sbFileMessageCreateParams = new SbFileMessageCreateParams(new SbFileInfo(pathToBigPhoto))
     {
         FileSize = size,
     };
    

I can specify the FileSize, or I can not transfer it, because it does not change anything

  1. If the file is less than 1 megabyte or it has time to go to the servers before receiving a “Request timeout” message, then the file is sent. And if not, then not

I will indicate my implementation of the method

    public static void SendPhotoToMyselfChannel(SbFileMessageCreateParams fileMessageCreateParams, SbMultiProgressHandler inProgressHandler, SbFileMessageHandler inCompletionHandler )
    {
        SendbirdProfile.MyselfChannel.SendFileMessage(fileMessageCreateParams, inProgressHandler,inCompletionHandler);
    }

Using the method:

public void TestSend()
{
    var sbFileMessageCreateParams = new SbFileMessageCreateParams(new SbFileInfo(pathToBigPhoto))
    {
        FileSize = size
    };

    SbExtentions.SendPhotoToMyselfChannel(sbFileMessageCreateParams,
        UploadHandler, OnCompleteHandler);
}

private void UploadHandler(string inRequestId, ulong inBytesSent, ulong inTotalBytesSent,
    ulong inTotalBytesExpectedToSend)
{
    var percent = inBytesSent / (float)inTotalBytesExpectedToSend;
    SetLoaderCircle(percent);
}

private void OnCompleteHandler(SbFileMessage inFileMessage, SbError inError)
{
    if (inError != null)
    {
        Debug.Log(inError.ErrorMessage);
        SetEmpty();
        return;
    }

    SetPhotoReady(bigSprite, inMessage.PlainUrl);
    onPhotoChanged?.Invoke();
    onSaveLocal?.Invoke(inMessage, bigSprite);
}

[Current impact]
My task is to create something like a social network where I use a profile photo and this profile can have several photos. I store them in a public channel assigned to the user. Something like this

    private static async void TryToCreateOpenChannel()
    {
        var postUrl = CurrenUser.GetMetaData(POST_WALL_URL);
        if (postUrl == null)
        {
            var postWallUrl = await CreateMyPostWall();
            var dictionary = new Dictionary<string, string>();
            dictionary.Add(POST_WALL_URL, postWallUrl);
            CurrenUser.CreateMetaData(dictionary, (newDictionaryInfo, inError ) => { });
        }
        else
        {
            SendbirdChat.OpenChannel.GetChannel(postUrl, (inChannel, inCache, inGetChannelError) =>
            {
                if (inGetChannelError != null)
                    return; // Handle error.

                inChannel.Enter((inCompleteHandler)=>
                {
                    MyselfChannel = inChannel;
                });
            });
        }
    }


    private static async Task<string> CreateMyPostWall()
    {
        var tsk = new TaskCompletionSource<string>();
        SbOpenChannelCreateParams openChannelCreateParams = new SbOpenChannelCreateParams();
        openChannelCreateParams.Name = USER_ID + "Wall";
        openChannelCreateParams.CustomType = "Wall";
        openChannelCreateParams.OperatorUserIds = new List<string> { USER_ID };

        SendbirdChat.OpenChannel.CreateChannel(openChannelCreateParams, (inChannel, inError) =>
        {
            if (inError != null)
            {
                tsk.SetResult(null);
                return;
            }

            tsk.SetResult(inChannel.Url);
        });

        return await tsk.Task;
    }

If I can’t solve the problem, I’ll either compress the image somehow, or use another approach to save photos (which I don’t really want, because your implementation is convenient)

Thank you!

Is there anyone here?
