- 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 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 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
- 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)
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.
* Include user_email in new user creation within get_user_object
Enhance the get_user_object function to include user_email in the parameters when creating a new user. This change is accompanied by a new test to verify that user_email is correctly included during the upsert process.
* Improve error handling in test_get_user_object by logging exceptions
Updated the test_get_user_object_upsert_includes_user_email function to log exceptions when they occur, enhancing the visibility of potential issues during testing. This change helps in diagnosing failures related to the mock LiteLLM_UserTable.
* fix(passthrough): raise_for_status in _async_streaming to propagate Azure 429s
* address greptile review feedback (greploop iteration 1)
Guard data/json args when content is provided to avoid httpx ValueError
* address greptile review feedback (greploop iteration 2)
Use bare raise to preserve original traceback in _async_streaming exception handler
* address greptile review feedback (greploop iteration 3)
Close httpx streaming response on error to prevent connection pool exhaustion
* address greptile review feedback (greploop iteration 4)
Guard aclose() call to prevent masking original exception; add explicit test for content param forwarding
* address greptile review feedback (greploop iteration 5)
Pass content to sign_request so AWS body-hash signing is correct when content is the sole body source
* revert sign_request content change - request_data expects dict, not bytes
Bedrock's sign_request calls json.dumps(request_data) — passing content bytes
would TypeError. sign_request should only receive data/json (dict), not raw bytes.
All operational/diagnostic messages in WebSearchInterceptionLogger are now
debug-level to avoid flooding production logs while still remaining available
when verbose logging is enabled.
