When a Gemini model supports system messages, messages with the system role get filtered out from the list of messages, so never appended to the content (and passed as system_instructions instead). This causes a 400 error, as both generateContent and streamGenerateContent require contents (the systemInstruction object is optional). This is a quick fix that does not check whether there was a system msg or if the model supports it. It simply makes sure that if the list of messages passed to _gemini_convert_messages_with_history() yields no contents, that there is at least a single (empty space) user message set to prevent the call from failing. The potential side effect of this is that we will not fail a call lacking any message at all, but if that needs to be checked (and AFAIU the OpenAI spec messages are required) it should be done elsewhere (e.g. validate_and_fix_openai_messages() @ litellm/utils.py). PS: Applied `make format` (`poetry run black [file changed]`) only to files changed by me. The `make lint` command identified a bunch of files requiring formatting that I am not modifying as I did not touch them. |

In total litellm runs 1000+ tests
[02/20/2025] Update:
To make it easier to contribute and map what behavior is tested,
we've started mapping the litellm directory in tests/litellm
This folder can only run mock tests.
