* fix(exception-mapping): map Gemini upstream-error body code 429 to RateLimitError
Some Gemini-compatible gateways (e.g. new-api) wrap a 429 rate-limit
signal from upstream inside an HTTP 500/503 envelope, with the real
code only surfaced in the JSON body:
{"error":{"message":"...high demand...","type":"upstream_error",
"param":"","code":429}}
Previously LiteLLM only looked at the HTTP status and mapped this to
InternalServerError, which Router treats as non-retryable for many
configs — so users got hard 500s instead of fallback/retry.
Now the Gemini/Vertex exception mapper parses error.code from the body
and routes code 429 to RateLimitError before falling through to the
HTTP-status branches. Other body codes fall through unchanged.
Tests cover:
- new-api gateway's `code:429` payload now maps to RateLimitError
- Genuine 500-body responses stay InternalServerError
- Non-JSON body strings fall through to status-code mapping unchanged
* fix(exception-mapping): scope body-code 429 promotion to 5xx envelopes
Addresses greptile P1/P2 + @Sameerlite's review on #30417. The new
elif branch was firing for any HTTP status, so a gateway response of
HTTP 400 with body {"error":{"code":429,...}} would be incorrectly
promoted to RateLimitError (retryable) instead of falling through
to BadRequestError. Same trap for 401 -> AuthenticationError.
Scoped the body-code 429 check to `500 <= status_code < 600` —
covers 500/502/503/504 (gateways wrapping upstream 429 in any 5xx
envelope) without inviting the 4xx misclassification.
Tests: parametrized table now covers 5xx (500/502/503), 4xx (400/401),
and the existing fall-through cases, asserting each maps to the
exception type that matches the HTTP status code. 50/50 pass locally.

[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/test_litellm
This folder can only run mock tests.
