# Let's completely remove API_KEY forwarding from llama_auth_headers and just leave it to default.
# WAIT. In start.sh I removed `env -u API_KEY`. So `llama-swap` now knows `API_KEY`.
# Since `llama-swap` knows `API_KEY`, we MUST provide it when sending requests from `gateway.py` to `llama-swap`.
# And we ARE doing that.
# What does `llama_auth_headers()` return now?

# If we are STILL getting Invalid API Key, and `API_KEY` is sent, maybe `llama-swap` doesn't support the `API_KEY` environment variable in the way we expect, OR it requires something else.
# Let's try passing the user's `key_from_header` straight to `llama-swap` if they provide one!
# Wait! We can't do that easily because `execute_completion` doesn't take the user's key.
# But wait, if `API_KEY` is set to "sk-gemini" (as you mentioned), and `gateway.py` sends `Authorization: Bearer sk-gemini`, why would `llama-swap` reject it?
# Let's check `llama-swap` docs. `llama-swap` expects the Bearer token to match the API_KEY environment variable.
# Wait, `llama_auth_headers` is using `LLAMA_API_KEY`! Let me check what I actually committed.
