When does this happen?

IF LiteLLM fails to recognize a model when using os.environ/VARIABLE_NAME syntax in config.yaml for Azure model configuration, but hardcoded values work.

How others solved it

THEN Ensure the .env file is in the same directory as your docker-compose.yml or referenced with an absolute path. Verify environment variables are present inside the container using 'docker exec -it <container> env'. Keep the .env file simple (no quotes around values, no comments) as Docker's --env-file support is limited. This issue is often a Docker configuration problem rather than a LiteLLM bug.

model_list:
  - model_name: mymodel
    litellm_params:
      model: azure/gpt-4o
      api_base: "os.environ/AZURE_API_BASE"
      api_key: "os.environ/AZURE_API_KEY"
      api_version: "os.environ/AZURE_API_VERSION"
