AttributeError: 'MessageRequest' object has no attribute 'user_id'

I'm trying to use MIRIX through the FastAPI endpoints you expose.

curl -X POST "http://localhost:47283/send_message" \
     -H "Content-Type: application/json" \
     -d '{"message": "Hello, can you introduce yourself?"}'
{"detail":"Error processing message: 'MessageRequest' object has no attribute 'user_id'"}

When hitting the /send_message endpoint, there's this error:

Error in send_message_endpoint: 'MessageRequest' object has no attribute 'user_id'
Traceback: Traceback (most recent call last):
  File "/home/sergio/Work/MIRIX/mirix/server/fastapi_server.py", line 550, in send_message_endpoint
    if request.user_id:

AttributeError: 'MessageRequest' object has no attribute 'user_id'

Our fastapi backend is designed to be used along with the front-end, so if you only use the backend, there would be issues.

You could either (1) use the frontend and backend together; or (2) use the python SDK instead (https://docs.mirix.io/user-guide/backend-usage/?h=sd#python-sdk-simplified-interface)

Thank you, will explore using the Python SDK in a simple fastapi implementation.
