From abba8e0102c48551c8ba402c71ec76a3d5653638 Mon Sep 17 00:00:00 2001 From: Tin Chi Lo Date: Fri, 31 Jul 2026 01:37:44 -0700 Subject: [PATCH] fix(ui): token change should not erase user-edited router configuration The prior fix for token-change races reset ALL configuration when the token changed, erasing user-edited tiers, keywords, semantic settings, and adaptive config alongside the preset selection and model-verification state. This was a regression: only the preset-tied state is token-scoped; user-entered config survives a token change. Revised: on token change, reset only the preset selection (setSelectedPreset), model load state, and the cached model list. The user's manually-edited complexity-router config, keywords, and adaptive settings persist. This closes the availability race without erasing user input. Updated test assertions to match the corrected design: "clears the preset selection" and "ignores a stale in-flight fetch". --- .../add_model/add_auto_router_tab.test.tsx | 26 ++++------------- .../add_model/add_auto_router_tab.tsx | 29 ++++++++----------- 2 files changed, 18 insertions(+), 37 deletions(-) diff --git a/ui/litellm-dashboard/src/components/add_model/add_auto_router_tab.test.tsx b/ui/litellm-dashboard/src/components/add_model/add_auto_router_tab.test.tsx index 751baaec4ee..b095a858eee 100644 --- a/ui/litellm-dashboard/src/components/add_model/add_auto_router_tab.test.tsx +++ b/ui/litellm-dashboard/src/components/add_model/add_auto_router_tab.test.tsx @@ -244,18 +244,11 @@ describe("AddAutoRouterTab", () => { expect(mockHandleAddAutoRouterSubmit).not.toHaveBeenCalled(); }); - // A caller switch must reset the form and re-enter the loading gate until the NEW caller's models - // arrive, or the previous caller's verified list keeps a preset selectable and submittable for a - // caller who may lack those models.
