From 355ae9989b9805a49650fe33d833619588957735 Mon Sep 17 00:00:00 2001 From: "devin-ai-integration[bot]" <158243242+devin-ai-integration[bot]@users.noreply.github.com> Date: Tue, 4 Aug 2026 19:05:39 +0000 Subject: [PATCH] fix(proxy): propagate user_email and bind api_key on JWT auth attribution paths (#34331) * fix(proxy): propagate user_email and bind api_key on JWT auth paths Standard JWT auth built UserAPIKeyAuth with user_id but never user_email, and the first auto-registered request early-returned a key with token set but api_key unset, so spend-log attribution logged user_api_key_user_email and user_api_key_hash as null. Bind api_key to the token hash on the auto-registered key, copy user_email from the resolved user object on both the standard and auto-register JWT paths, and warn when enable_jwt_auth/litellm_jwtauth are placed at the config top level where they are silently ignored.
