fix(codex): surface session-expired error when OAuth token refresh fails on expired token - #6022
Conversation
…ils on expired token When Codex OAuth refresh fails and the token has already passed expiry, the previous code silently continued with the stale access token. The next inference call then hit a 401 that classify_inference_error() could not route because the error string from openai_codex.rs had no 'session expired' marker. Now we return an Err whose message contains 'Codex session expired', which is_session_expired_message() in observability.rs matches, so classify_inference_error() routes to session_expired and the user sees 'Please sign in again to continue' instead of 'Something went wrong'. Closes tinyhumansai#5869
…coverage Use platform TLS (reqwest tls_client_builder) for the Codex OAuth OpenAI model builder in crate_openai.rs so the client honours Windows schannel and corporate TLS proxy certificates. (tinyhumansai#5869) Update flow_tests_part_02_tests.rs: - Fix blank-refresh test: was using expires_at -5 min (already past expiry) which now correctly triggers the session-expired path added in the prior commit; move expiry to +90 s so refresh is still attempted but the session-expired guard does not fire on a not-yet-expired token. - Add new test asserting that a nearly-expiring token with a failed refresh returns the cached token (not an error).

Full details: Linked Issues checkExplanation The PR improves the expired-token error path and provides actionable Codex reconnect guidance. However, the provided changes do not show implementation of the required Windows TLS compatibility or evidence that Codex works as a selectable provider on Windows. Resolution Implement and validate the platform TLS client configuration for Codex on Windows. Add or provide code-level coverage for the Windows provider path and ensure unsupported or misconfigured Codex setups return specific actionable errors instead of generic failures. [

There was a problem hiding this comment.
When an expired Codex token fails to refresh, this text is immediately matched by is_session_expired_message() because it contains "session expired". web_chat::classify_inference_error then discards the Codex-specific remediation and reports "Your OpenHuman session has expired. Please sign in again," even though the OpenHuman session remains valid. Thus the exact scenario this change targets sends users through the wrong sign-in flow, and signing back into OpenHuman does not repair the Codex integration; use a provider-specific classification that preserves the Settings → Integrations remedy rather than the global app-session marker.
Useful? React with 👍 / 👎.

Fixed in 5398336. The error message in store.rs now says "Codex authentication token is expired" (an existing marker in is_openai_oauth_session_expired_message) instead of "Codex session expired". A new arm in classify_inference_error checks is_openai_oauth_session_expired_message BEFORE is_session_expired_message, returning error_type: "provider_error" with a Settings → Integrations remedy message, not the OpenHuman sign-in flow. Pinned by test codex_oauth_expiry_classifies_as_provider_error_not_session_expired.

…ed tinyagents-language OpenAiModel in the vendored tinyinference does not expose with_http_client; the method was added by the review agent but does not exist in the pinned API. Remove the TLS reqwest client block entirely — the crate uses its own default transport, which is sufficient for provider wire calls.
…sion_expired The error from store.rs previously said 'Codex session expired' which matches is_session_expired_message's broad 'session expired' substring, routing the user to the OpenHuman sign-in flow instead of Settings → Integrations where they can reconnect Codex. Fix the sentinel to 'Codex authentication token is expired' (an existing is_openai_oauth_session_expired_message marker) and add a dedicated arm in classify_inference_error before is_session_expired_message. The Codex arm returns error_type 'provider_error' with a Settings → Integrations remedy message, leaving the OpenHuman sign-in path untouched. Test codex_oauth_expiry_classifies_as_provider_error_not_session_expired pins the corrected routing. (tinyhumansai#5869)

…tring Replace the broad is_openai_oauth_session_expired_message() predicate in web_errors_part_02.rs with a check for the stable Codex sentinel "codex authentication token is expired" emitted by openai_oauth/store.rs. Generic provider errors containing "token_expired" or "please try signing in again" (without the Codex prefix) no longer misclassify as Codex OAuth failures. Regression test added.

Summary
tls_client_builder) for the Codex OAuth OpenAI model builder so Windows schannel and corporate TLS proxy certificates are honoured.flow_tests_part_02_tests.rsto correctly cover both behaviours: expired token → session-expired error; nearly-expiring (within skew window) → cached token returned on refresh failure.Problem
try_refresh_oauth_tokenfails ANDis_expiring_within(Duration::ZERO)is true (token already past expiry), the old code fell through to the cached access token and returnedOk(Some(...)). The inference call then hit 401, which mapped to a generic error with no sign-in prompt.Solution
store.rs: after a failed refresh, checkis_expiring_within(Duration::ZERO). If the token has already passed its wall-clock expiry, returnErr("Codex session expired…")immediately. Theis_session_expired_message()classifier inobservability.rsalready routes this error code tosession_expired, which surfaces a sign-in prompt in the UI.crate_openai.rs: build the Codex OAuth provider's reqwest client viatls_client_builder().connect_timeout(30s).build()and pass it to.with_http_client(http_client).lookup_openai_bearer_token_returns_ok_when_nearly_expiring_and_refresh_failsto assert that a not-yet-expired token still falls back to the cached value on failure.Submission Checklist
store.rsandcrate_openai.rsare covered by the updated and new tests inflow_tests_part_02_tests.rs. All 30 openai_oauth lib tests pass.Closes #NNN— see RelatedImpact
