Is there an existing issue for the same bug?

• I have checked the existing issues.

Describe the bug and reproduction steps

Encountered the following error :

"litellm.BadRequestError: DeepseekException - Error code: 400 - {'error': {'message': 'deepseek-reasoner does not support successive user or assistant messages (messages[1] and messages[2] in your input). You should interleave the user/assistant messages in the message sequence.', 'type': 'invalid_request_error', 'param': None, 'code': 'invalid_request_error'}}"

I encounter the error when I use the DeepSeek Reasoner.

Thank you for the report! There is an issue on litellm repo on this: BerriAI/litellm#7972

Meanwhile, can you try to add to the command:

-e AGENT_ENABLE_PROMPT_EXTENSIONS=0
