* fix: graceful MCP OAuth revoke cleanup when tokens are missing (#12754) `maybeUninstallOAuthMCP` in `api/server/controllers/UserController.js` aborts before the DB-delete and flow-state cleanup steps whenever `MCPTokenStorage.getTokens` throws `ReauthenticationRequiredError` — which is exactly what happens when a user clicks "Revoke" on an MCP server whose backend is already dead and whose refresh token is gone. The resulting error is both surfaced to the log as a red line and, more importantly, leaks the DB token row and OAuth flow state. Wrap the token retrieval in try/catch following the same best-effort pattern already used for the two `revokeOAuthToken` calls. On `ReauthenticationRequiredError`, skip revocation silently (info log) and continue to the cleanup steps. On any other unexpected error, log a warning and continue — cleanup must always run. Exported `maybeUninstallOAuthMCP` for direct unit testing and added `api/server/controllers/__tests__/maybeUninstallOAuthMCP.spec.js` with 8 cases: early-return guards (non-MCP key, non-OAuth server, missing client info), happy path (both tokens revoked + cleanup), both failure-to-retrieve paths (ReauthenticationRequiredError and arbitrary error — cleanup still runs in both), single-token path, and revocation-call failures (cleanup still runs). Fixes #12754. * test: use instanceof check against real ReauthenticationRequiredError Follow-up to the previous commit on this branch. Two changes: 1. `UserController.maybeUninstallOAuthMCP` now checks `error instanceof ReauthenticationRequiredError` using the real class imported from `@librechat/api`, instead of comparing `error?.name === 'ReauthenticationRequiredError'`. The name-string check matched any unrelated error that happened to have the same `.name`; the `instanceof` check is a proper identity test. 2. The accompanying spec's jest mock for `@librechat/api` now exposes a `ReauthenticationRequiredError` class, and the test imports it from that mock so the `instanceof` comparison in the production code holds during the test. Without this, the two "skips revocation ... still runs cleanup" tests threw `TypeError: Right-hand side of 'instanceof' is not an object` because the mock left the class undefined. All 8 tests in the spec pass. |
