Why data incompatible with tuples format?

[FlyerW]

Dear Maintainers,

First of all, thank you for your amazing work on this project. I hope you are having a great holiday season and Happy New Year! 🎉
I encountered an issue while running the following command:
python -m demo.app --resume_from_checkpoint chenjoya/videollm-online-8b-v1plus

The application starts correctly, and I can access the Gradio interface at the provided URL. However, when interacting with the chatbot, I receive the following error message:
gradio.exceptions.Error: 'Data incompatible with tuples format. Each message should be a list of length 2.'

The chatbot raises an exception related to an incompatible data format. It seems the returned data does not match the expected tuples format.

Additional Information:
Python version: 3.12
Gradio version: 5.7.1

Traceback (most recent call last): File "/local/sean/miniconda3/lib/python3.12/site-packages/gradio/queueing.py", line 624, in process_events response = await route_utils.call_process_api( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/local/sean/miniconda3/lib/python3.12/site-packages/gradio/route_utils.py", line 323, in call_process_api output = await app.get_blocks().process_api( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/local/sean/miniconda3/lib/python3.12/site-packages/gradio/blocks.py", line 2029, in process_api data = await self.postprocess_data(block_fn, result["prediction"], state) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/local/sean/miniconda3/lib/python3.12/site-packages/gradio/blocks.py", line 1835, in postprocess_data prediction_value = block.postprocess(prediction_value) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/local/sean/miniconda3/lib/python3.12/site-packages/gradio/components/chatbot.py", line 551, in postprocess self._check_format(value, "tuples") File "/local/sean/miniconda3/lib/python3.12/site-packages/gradio/components/chatbot.py", line 349, in _check_format raise Error( gradio.exceptions.Error: 'Data incompatible with tuples format. Each message should be a list of length 2.'

Could you help me identify the correct format for the chatbot data? Should I modify the chatbot response to use the new messages format with keys role and content, as suggested in the warning message?

Thank you for your time and assistance! I wish you a wonderful new year. 🎊

Best regards,
Sean
