N/A

When following the example in this doc without the proxy extra installed, I get the following error

15:54:27 - LiteLLM:ERROR: litellm_logging.py:2583 - [Non-Blocking Error] Error initializing custom logger: Missing dependency No module named 'backoff'. Run `pip install 'litellm[proxy]'`

During handling of the above exception, another exception occurred:
