TypeError: AsyncLLMEngine.generate() got an unexpected keyword argument 'prompt'

I installed ochat into new venv with pip3 install ochat.

Then I run the server with python -m ochat.serving.openai_api_server --model openchat/openchat-3.6-8b-20240522 --model-type openchat_3.6

However, when trying curl curl http://localhost:18888/v1/chat/completions -H "Content-Type: application/json" -d '{ "model": "openchat_3.6", "messages": [{"role": "user", "content": "You are a large language model named OpenChat. Write a poem to describe yourself"}] }'

I get Internal server error. Server prints this:

any idea where the problem might be?
