* fix(responses-api): raise APIError on in-stream error events; widen ErrorEventError.param - BaseResponsesAPIStreamingIterator._maybe_raise_for_error_event inspects each chunk and raises litellm.APIError for type=error and type=response.failed events so callers see an exception instead of a benign stream chunk - rate_limit* codes map to 429; client error codes (invalid_request_error, context_length_exceeded, etc.) map to 400; all other codes default to 500; raw integer codes are never used as-is as HTTP status codes - ErrorEventError.param widened from Optional[str] to Optional[Union[str, Dict]] to prevent Pydantic ValidationError on dict-typed param payloads silently dropping error events before any type inspection * test(responses-api): add streaming iterator error event tests to CI-covered path * test(responses-api): cover response.failed, dict-error, null-error, and sync iterator paths * test(responses-api): set completion_start_time on mock logging objects for internal staging _process_chunk * fix(responses-api): map insufficient_quota to 429, derive failed-response log status from error code, and record failed-stream usage for spend accounting insufficient_quota moves out of the 400 bucket; OpenAI returns HTTP 429 for it and the non-streaming exception mapping treats 429 as RateLimitError, so the in-stream mapping now agrees _handle_logging_failed_response previously hardcoded APIError(status_code=500), so a rate-limited response.failed was logged to integrations as 500 while the caller saw 429; it now shares the same error-code-to-status mapping via _error_event_fields and _status_code_for_error_code usage carried on a response.failed event is now stashed as combined_usage_object with its computed cost on the logging object before failure handlers run, reusing the mid-stream-interruption spend recovery path (_failure_handler_helper_fn, proxy post_call_failure_hook, _ProxyDBLogger), so failed streams count their billed tokens instead of logging zero cost dedupe: TestMaybeRaiseForErrorEvent in tests/llm_responses_api_testing duplicated tests/test_litellm/responses/test_streaming_iterator_error_events.py, which is the canonical mirrored location and CI-covered via test-unit-responses-caching-types; the duplicate class is removed * fix(responses-api): wrap retriable in-stream errors in MidStreamFallbackError and map error type field to status Mirror chat streaming semantics from _handle_stream_fallback_error: 429 and 5xx in-stream error events now raise MidStreamFallbackError carrying the mapped APIError so the router's FallbackResponsesStreamWrapper triggers mid-stream fallback and cooldown; non-retriable 4xx still raise APIError directly. Status mapping now reads both the OpenAI error type and code fields, so type-classified client errors (e.g. invalid_request_error with code invalid_prompt) map to 400 instead of falling through to 500. * fix(responses-api): accumulate streamed output text so mid-stream fallback continues instead of restarting MidStreamFallbackError was always raised with generated_content="", so the router's stream_with_fallbacks treated every mid-stream error as pre-first-chunk and retried with the original input, streaming duplicated content to clients that had already received partial output. The iterators now accumulate response.output_text.delta text (mirroring chat's response_uptil_now) and pass it as generated_content, letting the router build a continuation input via _build_responses_continuation_input. * test(responses-api): pin in-stream token limit error to raised APIError --------- Co-authored-by: Deepanshu <deepanshu.lulla@alpha-sense.com> |
