Bug Report

Description

Bug Summary:
I have setup a litellm proxy. Both the containers (open-webui and litellm proxy) are running properly. I can access my litellm-proxy endpoint and query the model list from open-webui container console (python interpreter -> get model list by passing the master_key). However, on loading the open-webui, the model list only shows ollama models and not the litellm models I configured. I get this error:

webui-1         | http://openai-proxy:8000/v1/models sk-123456789qwerty
webui-1         | Error loading request body into a dictionary: Expecting value: line 1 column 1 (char 0)
webui-1         | INFO:     192.168.65.1:22222 - "GET /openai/api/models HTTP/1.1" 200 OK

Looks like the GET requests succeeds but the json is not loaded properly.
I tried to get the josn list myself inside the open-webui container and I see the request is successful. Can you please help me fix this?

Steps to Reproduce:
Here's my docker-compose.yml:

version: '3.9'

services:
  webui:
    image: ghcr.io/ollama-webui/ollama-webui:main
    environment:
      - "OLLAMA_API_BASE_URL=http://host.docker.internal:11434/api"
      - "OPENAI_API_BASE_URL=http://openai-proxy:8000/v1"
      - "OPENAI_API_KEY=sk-123456789qwerty"
    ports:
      - 3000:8080
      - 11434:11434
    volumes:
      - ./ollama-webui/data:/app/backend/data
    restart: unless-stopped

  openai-proxy:
    image: ghcr.io/berriai/litellm:main-latest
    environment:
      - "MASTER_KEY=sk-123456789qwerty"
      - "OPENAI_API_KEY=${OPENAI_API_KEY}"
      - "MISTRAL_API_KEY=${MISTRAL_API_KEY}"
      - "ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY}"
    ports:
      - 4000:8000
    volumes:
      - ./litellm/config.yaml:/app/config.yaml
    command: [ "--config", "/app/config.yaml", "--port", "8000" ]
    restart: unless-stopped

Here's my litellm config:

model_list:
  - model_name: anthropic-claude-instant-1.2 
    litellm_params:
      model: anthropic/claude-instant-1.2
      api_key:"PLACEHOLDER_API_KEY" # this is correctly set
  - model_name: anthropic-claude-v2.1
    litellm_params: 
      model: "anthropic/claude-2.1"
      api_key: "PLACEHOLDER_API_KEY" # this is correctly set

litellm_settings: # module level litellm settings - https://github.com/BerriAI/litellm/blob/main/litellm/__init__.py
  drop_params: True
  set_verbose: True

general_settings: 
  master_key: sk-123456789qwerty

Expected Behavior:
Model list shows up via litellm proxy and shows anthropic models

Actual Behavior:
Error when trying to list all the models

Environment

Try changing OPENAI_API_BASE_URL=http://openai-proxy:8000/v1 to OPENAI_API_BASE_URL=http://host.docker.internal:4000/v1. I've had some issues where the LiteLLM proxy doesn't like to listen from the internal container network.

Wow that was quick! Thank you so much @justinh-rahb! Really appreciate it. This fixed the issue. Although I am not sure why. Seems like litellm could get and send response fine with the openai-proxy url?

Your guess is as good as mine, I didn't feel like debugging it so just went with what worked at the time 😬 I've since remove the LiteLLM container from my WebUI stack because it's now built-in to the project and can be configured from the Settings > Models interface.
