zoveki 3b9a59348f fix(vertex_ai)!: send the caller's anthropic-version in the Vertex Claude /v1/messages body, not the header (#48814) ... * fix(vertex_ai): drop the caller's anthropic-version header on Claude /v1/messages Vertex reads the API version from the body's anthropic_version and answers 400 when a forwarded anthropic-version header names a different one, which anthropic SDK 2.x always does. Strip the header on the Python and LITELLM_RUST Vertex messages routes. * fix(vertex_ai): carry the caller's anthropic-version into the Claude /v1/messages body Vertex reads the API version from the body alone, so the caller's anthropic-version header now becomes the body's anthropic_version instead of a pinned vertex-2023-10-16. The 2023-01-01 and 2023-06-01 first-party versions keep vertex-2023-10-16, and the header itself is still never sent. Same change on the Python proxy and the Rust gateway. * fix(vertex_ai): follow drop_params for an anthropic-version Vertex does not accept Only versions Vertex accepts in the body (vertex-2023-10-16, 2026-10-21) are carried into anthropic_version. 2023-06-01, 2023-01-01, a blank header, or no header keep vertex-2023-10-16. Any other value drops to vertex-2023-10-16 under drop_params and answers a 400 naming drop_params without it, on the Python proxy and the Rust gateway. * refactor(vertex_ai): return the unsupported anthropic-version error as a value and keep Rust helpers and tests in place * fix(rust gateway): resolve os.environ drop_params and accept the same flag words as Python The gateway read drop_params: os.environ/NAME and words like yes as off, so the drop_params opt-out from the new anthropic-version 400 did not work there * docs(rust router): name Router::from_config in the crate README --------- Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com>		2026-10-28 18:06:58 -07:00
