fix(azure)!: answer 401 when Entra rejects the deployment's credential (#49863)
* fix(azure): answer 401 when Entra rejects the deployment's credential A ClientAuthenticationError from the Entra token provider (wrong, expired or rotated client secret) used to surface as a retryable 500 carrying the app's client id and Entra trace ids. Map it to a 401 AuthenticationError that keeps the AADSTS code and first sentence with GUIDs redacted, on both the direct token fetch and the provider handed to the OpenAI SDK client. Network failures stay 500. * fix(azure): keep network failures to Entra a retryable 500 azure-identity wraps a transport failure in ClientAuthenticationError, so the 401 mapping now skips errors whose cause chain holds ServiceRequestError or ServiceResponseError * fix(azure): cover async token providers and Entra 5xx, and scope caller-sent Entra credentials * fix(azure): map only AADSTS-coded Entra rejections to 401 and keep caller credential failures out of cooldown An Entra ClientAuthenticationError now answers 401 only when its message carries an AADSTS code, its HTTP status is not 429 or 5xx, and the code is not the AADSTS50196 throttle, so a chained credential's outage or throttle stays a retryable error. Caller-sent Entra fields no longer change the deployment id; a 401 from a value the caller sent skips the shared deployment's cooldown instead. The Azure AI Foundry agent token fetch maps the same rejection, and the A2A endpoint answers it with HTTP 401. * fix(router): count router default_litellm_params as configured Entra credentials when deciding cooldown * fix(azure): keep transient Entra codes retryable and scope 401 handling to Entra rejections ClientSecretCredential drops Entra's HTTP status, so throttling and transient codes (AADSTS50033, 50196, 90006, 90024, 90033, 90055) now stay retryable instead of mapping to 401. The A2A endpoint answers 401 only for an AuthenticationError caused by an Entra token rejection, and the router skips cooldown for a caller-sent Entra field only on Azure-family deployments. The azure/ Decisions route and the Bing grounding search tool now map an environment-credential rejection to the same 401. * fix(azure): map only known Entra credential rejections to 401 and cover the OIDC token exchange Unlisted AADSTS codes keep the retryable 500, the router skips the 401 cooldown only when an Entra rejection caused it, and a federated token Entra rejects answers the same 401 on Azure chat, Responses and A2A agents * fix(azure): answer 401 for Entra rejections on the /azure passthrough and token counting The fallback hop skips cooldown when Entra rejected a credential the caller sent, Prometheus counts a deployment's own Entra rejection as a deployment failure again, and an OIDC exchange error keeps Entra's headers so Retry-After reaches the router. * fix(azure): keep a no-op caller Entra field from skipping cooldown and redact the passthrough 401 message A caller-sent Entra field now skips the deployment's cooldown only when it differs from the deployment, its named credential, the router defaults, the AZURE_* environment variables and the default scope. An empty value counts as unset, so a deployment whose own secret is wrong still cools down when the caller's field changes nothing about the token request. The /azure passthrough's Entra 401 message goes through the same internal hostname redaction as other client-facing errors. * fix(router): compare a caller's Entra field with the value the deployment uses A caller-sent Entra field skipped the cooldown only when it matched no configured source, so a value equal to an environment default the deployment overrides (a stale AZURE_CLIENT_SECRET, say) counted as the deployment's own and let a caller's rejected credential cool down a working deployment. The check now resolves the value the deployment would use without the caller, in order from the router defaults, the deployment, its named credential, the AZURE_* environment variables and the default scope, and skips the cooldown only when the caller's value differs from it. * fix(azure): follow the settings merge for empty Entra fields and keep non-rejection OIDC exchange errors unchanged * fix(azure): count only the failed attempt's Entra rejection and ignore a non-callable token provider * fix(azure): keep the streaming Entra rejection inside the failed attempt --------- Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com>
