* fix(responses): map streamed flex_unavailable errors to 429 not 500 When OpenAI has no flex capacity, a service_tier flex request fails with type resource_unavailable / code flex_unavailable. Non-streamed, this arrives as HTTP 429 and litellm raises RateLimitError. Streamed /v1/responses delivers the same error as an in-stream event, and neither field was in _ERROR_CODE_HTTP_STATUS, so it defaulted to 500 InternalServerError. The HTTP status then depended only on stream: one provider outage looked like a 429 or a 500. The 500 reads as a server error in metrics and alerting, and callers that retry on 429 do not retry it. Map both resource_unavailable and flex_unavailable to 429 so the streamed path matches the non-streamed path. Fixes #49736 * test(responses): cover streamed flex outage end to end for error and response.failed events Streams the flex_unavailable payload from #49736 through litellm.aresponses with an injected client and asserts a 429 RateLimitError for both in-stream event kinds, matching the non-streamed path * test(responses): drop explanatory comment from flex status mapping test * test(integration): cover streamed flex outage status on responses and chat bridge Drives the flex_unavailable payload from #49736 through a real proxy as an in-stream error event and as response.failed. The native /v1/responses stream fails with rate_limit_exceeded and logs 429, and the chat bridge answers a 429 throttling error, where both reported a 500 before the mapping fix --------- Co-authored-by: BinYi LIU <bliu1@berkeley.edu> |

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/unit
This folder can only run mock tests.
