Commit 1cdda28b6 changed "openrouter/openai/gpt-5.2-codex" to mode "responses",
but this broke GPT-5.2-Codex with OpenRouter:
```
response = await litellm.acompletion(
model="openrouter/openai/gpt-5.2-codex",
messages=[{"role": "user", "content": "Hello"}],
api_key=os.environ.get("OPENROUTER_API_KEY"),
)
```
crashes with: `OpenrouterException - argument of type 'NoneType' is not iterable`
Responses API is in beta in OpenRouter and no other OpenRouter models use "responses"
mode. The commit that changed this probably did it by mistake.
Therefore change the mode to "chat" and fix the crash.
When an OpenAI-compatible upstream provider emits minimal streaming event
payloads that omit required fields (e.g. created_at, output, output_index,
content_index), Pydantic raises a ValidationError crashing the SSE stream
and returning HTTP 500.
Fall back to model_construct() on ValidationError, consistent with the
existing pattern in transform_response_api_response for non-streaming.

Notes: General support for Opus 4.6 was added in #20506 however
it omitted the AU (australian) specific instance profile used
in Bedrock. This change only adds the the au id. It is copied
from the US model settings which is consistent with past
additions of this regional model profile.
Keycloak (and similar OIDC providers) include role claims in the JWT
access token but not in the UserInfo endpoint response. Previously,
roles were only extracted from UserInfo, causing all SSO users to
default to internal_user_view_only regardless of their actual role.
Changes:
- Extract user roles from JWT access token in process_sso_jwt_access_token()
when UserInfo doesn't provide them (tries role_mappings first, then
GENERIC_USER_ROLE_ATTRIBUTE)
- Handle list-type role values in get_litellm_user_role() since Keycloak
returns roles as arrays (e.g. ["proxy_admin"] instead of "proxy_admin")
- Add 9 new unit tests covering role extraction and list handling
- Update 3 existing tests for new JWT decode behavior
Closes#20407
- process_mcp_request() now falls back to OAuth2 passthrough when Authorization header contains a non-LiteLLM token (catches HTTPException and ProxyException 401/403)
- MCPClient._get_auth_headers() adds missing MCPAuth.oauth2 case
* Warn when budget lookup fails; cache won't populate
- Add _log_budget_lookup_failure helper in auth_checks.py
- Log at WARNING in get_user_object, get_team_object, get_key_object
when DB lookups fail (schema mismatch, etc.)
- Add schema migration hint for prisma/db errors
- Add dry-run test for _log_budget_lookup_failure
* fix: skip budget lookup failure log for expected user-not-found case
Avoid logging 'cache will not be populated' when the user simply doesn't
exist - not caching is correct behavior in that case. Only log for
unexpected errors (schema, DB, etc.) where the message is meaningful.
