* fix(bedrock): keep x-amzn-RequestId on chat error responses
Bedrock chat error paths built BedrockError from only a status code and a
message, so the provider response headers were gone before exception mapping
ran and the proxy had nothing to forward. AWS support needs x-amzn-RequestId
to investigate a server-side error.
- converse and invoke chat handlers pass the real headers and response when
they turn an httpx.HTTPStatusError into a BedrockError, and read the body
through error_response_text so a streamed body nobody read does not throw
- every bedrock chat get_error_class honors the headers it is already handed:
invoke, moonshot, bedrock-hosted openai, agentcore and the invoke agent
- BedrockError carries those headers into the response it synthesizes when a
caller has headers but no response, skipping values httpx cannot carry
- the bedrock 500 mapping forwards the provider response like its 4xx and 503
siblings instead of fabricating a blank one
The proxy now returns llm_provider-x-amzn-requestid on Bedrock chat errors.
* fix(bedrock): keep request-id on text-classified errors
The context-window and image branches of _map_bedrock_exception built their
litellm exception without the provider response, so a Bedrock 400 classified
by its body text lost x-amzn-RequestId while the sibling branches kept it.
Also narrows the new BedrockError types and trims its docstrings.
* chore(bedrock): drop the docstrings on the new error helpers
* fix(bedrock): keep request-id on every error path that has one
The ticket's root cause is that every BedrockError raise site under
litellm/llms/bedrock/ was built from status and message alone. The first
commits covered the chat and invoke handlers; this covers the rest.
Embeddings, rerank, image generation, image edit, count tokens, search and
the transformation layers now hand on the provider response or its headers,
and both bedrock_mantle configs return a BedrockError instead of the
OpenAI error that drops them.
Two blockers surfaced while verifying the streaming path. The trailing
`except Exception` in make_call and make_sync_call swallowed the BedrockError
raised a few lines above, relabelling a provider status as a 500, and the
non-200 branch read an unread streamed body, which throws.
The raise sites left alone have no provider response to carry: timeouts,
credential and config errors, and mid-stream event frames.
* fix(bedrock): forward provider headers from the count tokens route
The count tokens route converts BedrockError into an HTTPException, and dropped
the headers the handler had just kept, so that route still lost the request id.
get_response_headers now takes a Mapping so an httpx.Headers can be handed to it
without a copy.
* fix(bedrock): classify every bedrock surface through BedrockError
Eleven bedrock configs still inherited a provider-agnostic get_error_class
that builds a blank response, so the request id was gone before the proxy
read it. Claude platform, bedrock anthropic-messages, both image edit
configs, passthrough, realtime, vector stores and agentcore search now
return BedrockError, and a parametrized audit drives all 36 configs.
* fix(proxy): keep provider headers on the httpx status error branch
_handle_llm_api_exception forwards safe_headers on every branch except the
httpx.HTTPStatusError one, which the bedrock passthrough route reaches, so
the request id was dropped before the client saw the response.
* fix(bedrock): keep the request id on the timeout mappings
Timeout takes no response argument, so the three bedrock timeout branches
dropped the provider headers even when the upstream answered 408 or 504
with an x-amzn-RequestId. They now ride on the exception, already
llm_provider-prefixed, which is the form the proxy emits.
* fix(bedrock): keep the provider response on mapped timeouts
The previous round attached llm_provider-prefixed headers directly to the
Timeout. That shadowed the raw upstream headers for _get_response_headers,
so router cooldown and fallback cooldown stopped honouring retry-after on
bedrock 408/504 replies.
Give Timeout an optional response instead, the way every other mapped
bedrock exception already carries one. Retry logic reads the raw
retry-after off the response, and the proxy prefixes those headers on the
way out, so clients still see llm_provider-x-amzn-requestid.
* chore(bedrock): drop the explanatory comment on Timeout.response
