Also document the sessionStorage cross-tab trade-off: per-tab scope
means users behind an HttpOnly proxy must log in once per tab, but
this is intentional to avoid localStorage XSS exposure.

Replace local getCookie functions in page.tsx and user_dashboard.tsx
with the shared one from cookieUtils that has the sessionStorage
fallback. Without this, the HttpOnly cookie fix was incomplete —
page.tsx (the dashboard entry point) could not read the token,
causing the redirect loop to persist.
Also scope the sessionStorage fallback to the "token" key only,
and clear sessionStorage in page.tsx deleteCookie.

Replace setTokenCookie (which is a no-op when reverse proxy adds HttpOnly)
with storeLoginToken using sessionStorage. Add sessionStorage fallback to
getCookie so the token is found even when the cookie is HttpOnly. Also handle
'=' in cookie values with .slice(1).join("=") and clear sessionStorage on
logout.

- Add loginCall integration tests verifying setTokenCookie is called with
token and skipped when absent (backward-compatibility path)
- Use encodeURIComponent/decodeURIComponent in setTokenCookie/getCookie

When LiteLLM is behind nginx-ingress or similar with security-hardened
configs, the reverse proxy adds HttpOnly to all Set-Cookie headers. This
makes the JWT token unreadable by JavaScript, causing an infinite login
redirect loop. Fix by returning the JWT token in the /v2/login response
body so the frontend can set a JS-accessible cookie directly.

The empty-line filter in __next__/__anext__ called .strip() without
checking the type first. When the Responses API yields Pydantic
BaseModel events (e.g. ResponseCreatedEvent), this raises
AttributeError. Add an isinstance(str_line, str) guard so non-string
objects pass through to _handle_string_chunk as intended.

Extract the single-server branch of list_tool_rest_api into a dedicated

* fix(sso): add direct PKCE token exchange and Redis cache wiring for multi-instance SSO
When PKCE is enabled, bypass fastapi-sso and perform direct token exchange so
code_verifier is correctly included. Store PKCE verifiers as dict in cache
for proper JSON serialization in Redis. Wire user_api_key_cache to Redis when
available so PKCE verifiers are shared across ECS tasks/pods.
Also adds clearer error messages when PKCE is required but not configured.
* refactor(sso): extract PKCE token exchange into SSOAuthenticationHandler methods
- Move import httpx/jwt to module level (top of file, not inside function)
- Extract inline PKCE token exchange + userinfo logic into two static methods:
_pkce_token_exchange() and _get_pkce_userinfo()
- get_generic_sso_response PKCE path is now a single method call
- Fix double-logging in except block for non-PKCE errors
- Use %-style log formatting (no f-strings in log calls)
* fix: address greptile review feedback
- Fix access_token missing in PKCE path: read from combined_response directly
instead of generic_sso.access_token (which is only set by verify_and_process)
- Fix PKCE error hint firing when PKCE is already enabled: only show
'set GENERIC_CLIENT_USE_PKCE=true' advice when code_verifier was absent
- Fix unguarded KeyError on access_token: check for error field in HTTP 200
responses before accessing token_response['access_token']
- Fix silent empty userinfo: raise ProxyException when both userinfo endpoint
and id_token fallback produce no user data
- Fix backward-incompatible Redis wiring: only attach Redis to user_api_key_cache
when GENERIC_CLIENT_USE_PKCE=true, preserving existing in-memory behaviour
* fix: address second round of greptile review feedback
- Fix PKCE error hint: check env var directly (not code_verifier presence) to
distinguish 'PKCE not configured' from 'PKCE enabled but cache miss'
- Fix misleading Redis TTL comment in proxy_server.py
* fix: address third round of greptile review feedback
- Fix CRITICAL log firing on every non-PKCE callback: only log when PKCE is enabled
- Remove unused pkce_env_value intermediate variable
- Prefer reusing redis_usage_cache over creating separate RedisCache instance
(avoids losing advanced connection options like SSL, timeouts, db)
* fix: address fourth round of greptile review feedback
- Strip OAuth token credentials from response_convertor input to prevent
access_token/id_token appearing in restricted-group error messages
- Reuse single httpx.AsyncClient for both token exchange and userinfo requests
to avoid a second TCP/TLS handshake per SSO callback
- Revert Redis wiring to user_api_key_cache: PKCE code already uses
redis_usage_cache directly; wiring would route all API-key lookups through
Redis unnecessarily. Add startup warning instead when PKCE+Redis mismatch.
- Move _OAUTH_TOKEN_FIELDS to module level
* fix remaining PKCE test assertion for dict-format verifier storage
* sanitize PKCE cache log to not expose verifier content
* address greptile review feedback (greploop iteration 3)
* address greptile review feedback (greploop iteration 4)

- read GENERIC_CLIENT_USE_PKCE env var once in prepare_token_exchange_parameters
- include actual decode error in jwt.decode failure exception message
- add GENERIC_CLIENT_USE_PKCE=true to no-state regression test
* defer PKCE verifier deletion until after all downstream processing
Move _delete_pkce_verifier to after response_convertor and
process_sso_jwt_access_token complete. If JWT processing raises,
the verifier stays in cache so the user can retry without restarting
the full OAuth flow.
* address greptile review feedback (greploop iteration 38)
- fix strict-mode cache miss error message to differentiate
cross-instance routing failures (Redis configured) from single-instance
issues (TTL expiry, pod restart) when only in-memory cache is available
- add comment above _get_pkce_userinfo call explaining that bearer
credentials are always sourced from token_response in the merge step
* fix null JSON response body in _pkce_token_exchange
- Guard against HTTP 200 with body null: response.json() returns None
for JSON null, and calling .get() on None raises AttributeError.
Now raises a clean ProxyException with a clear error message.
- Fix misleading userinfo warning: was always saying "empty dict" but
also fires for JSON null responses; updated to say "empty or null".
- Add HTTP status code assertion to cache miss test.
* address greptile review feedback (greploop iteration 39)
- fix credential leakage: directly assign received_response from
combined_response instead of relying on nonlocal mutation; Pyright
was flagging the old guard as unreachable, meaning credential stripping
might not execute — now it always runs unconditionally
- add test for legacy plain-string cache format backward compat branch
- add test for HTTP 200 with no error field and no access_token (else branch)
- add test for HTTP 200 with JSON null body (new AttributeError guard)
* fix _OAUTH_TOKEN_FIELDS merge loop to preserve userinfo values on absent fields
When the token endpoint omits a bearer-credential field entirely (field
absent from token_response), the previous code deleted it from merged even
if userinfo provided a valid value. Now:
- non-null in token_response → restore authoritative token endpoint value
- explicit null in token_response → remove key from merged (clean absence)
- field absent from token_response → leave userinfo value unchanged
* use HTTP 401 for PKCE missing config errors
GENERIC_CLIENT_ID and GENERIC_TOKEN_ENDPOINT missing when PKCE is
enabled are auth-flow failures, not server errors. Use 401 instead
of 500 to avoid triggering false-positive server error alerts in
monitoring systems.
* address greptile review feedback (greploop iteration 40)
- fix duplicate error logging: demote first format-error log to DEBUG
so the detailed ERROR in strict-mode branch is not duplicated
- add HTTP status code assertions to all PKCE ProxyException tests
for better regression protection against accidental code changes
* add credential absence assertions to test_pkce_token_exchange_basic_auth
Verify that client_id and client_secret are NOT double-sent in the POST
body when Basic Auth is used (include_client_id=False with client_secret).
Catches regressions where credentials leak into both Auth header and body.
* address greptile review feedback (greploop iteration 41)
- add Bearer token header assertion to test_pkce_token_exchange_credentials_in_body
- add cache query assertions to both non-strict mode tests to confirm
the cache was accessed before the warning path triggers
* address greptile review feedback (greploop iteration 42)
- assert null id_token is absent from merged result in basic auth test
- add test for HTTP 200 empty/null userinfo body with no id_token fallback
* use caplog to verify warning logs in non-strict cache miss tests
The two non-strict mode tests now use pytest's caplog fixture to assert
that a warning is actually emitted, not just that the code continues
without raising. This catches regressions where the warning silently
disappears.
* remove dead-code response=None guard in _pkce_token_exchange
* clean up stale pkce verifier cache entries in non-strict mode
* fix test: configure async_delete_cache as AsyncMock and assert cleanup called
* add sentinel guard so pkce-no-redis warning only fires once across hot-reloads
* fix misleading comments: code_verifier init and bearer-credential merge docs
* add best-effort cleanup in strict-mode for corrupt/empty cache entries
* add redirect_uri assertion, userinfo body in non-200 log, sentinel comment
OpenAI rejects any reasoning_effort (even 'none') with tools in
/v1/chat/completions for gpt-5.4. Update the guard to drop reasoning_effort
regardless of value. Add docs explaining the auto-drop behavior.
Remove dead routing condition (is_model_gpt_5_4_plus_model) that
prevented reasoning_effort from being dropped when tools are present.
The Responses API routing was never merged, so the guard was a no-op
that broke the drop logic introduced by 14b52b1318 on main.
