Describe the bug

Getting invalid message type when using Image message with latest OpenAI (it supports image starting version 4)

Steps to reproduce

Created a C# app with AutoGen and OpenAI version 0.0.16. Try to send an Image message along with a text message.

For the piece of code like:

var image = await File.ReadAllBytesAsync(imagePath);
            var imageMessage = new ImageMessage(Role.Assistant, BinaryData.FromBytes(image, "image/jpg"));
            var reply = await agent.SendAsync("[query message]", [imageMessage]);

Model Used

gpt-4o/gpt-4o-mini

I try the Image_Chat_With_Agent tutorial with gpt-4o-mini and it's working. So could you share the code and full stack trace, the one you shared above is not complete?

[CyborTronik]

@LittleLittleCloud updated the stack trace and added few details

[LittleLittleCloud]

@CyborTronik Did you register the message connector?
