Language runtime version: Python 3.13.1
Package version: google-genai 0.5.0

async with self.client.aio.live.connect(model=MODEL, config=CONFIG) as session: await session.send( input={ "data": encoded_data, "mime_type": mime_type }, end_of_turn=True )

When the data is base64 encoded image and mime_type is image/jpeg the model does not return a response unless prompted with text. For example when I have a system_instruction to call a function whenever there is red object detected in the image the and then I start sending the image base64 input the model does not respond but If I prompt with text something like "Do you see the red object" after every base64 image input I do see a response.

Is there an update on this issue? Is it due to the library or is it due to an issue with the gemini service ?
