Fixes #3467

Summary

When Google Antigravity (Cloud Code Assist API) rejects a request due to an unsupported geographic region or datacenter IP (HTTP 400 with FAILED_PRECONDITION: User location is not supported for the API use.), OpenCodeX previously classified it as:

Provider error 400: Antigravity invalid request: User location is not supported for the API use.

and downstream OpenAI-compatible endpoints translated this into type: "invalid_request_error".

Changes

  1. src/lib/errors.ts:

    • Defined LOCATION_UNSUPPORTED_PATTERNS containing location/region/country restriction patterns.
    • Added isLocationUnsupportedMessage(text) that lowercases input once and validates location cues.
    • In classifyError(), mapped location-unsupported messages and type === "location_not_supported" to type: "permission_error", code: "location_not_supported".
  2. src/adapters/google-errors.ts:

    • Imported and re-exported LOCATION_UNSUPPORTED_PATTERNS and isLocationUnsupportedMessage (as GOOGLE_LOCATION_UNSUPPORTED_PATTERNS and isGoogleLocationUnsupportedText), eliminating code duplication.
    • In classifyGoogle(), matched location/region restriction messages before the generic status === 400 / "invalid" fallback. The classified label is now ${label} location not supported.
  3. src/adapters/google-http.ts:

    • In normalizeFinalGoogleError(), logged an actionable diagnostic warning to console when a location restriction is encountered, advising the operator to inspect their TUN mode, proxy settings, or IPv6 routing leaks.
  4. Tests:

    • Added unit test coverage in tests/google-errors.test.ts for location-unsupported classification.
    • Added unit test coverage in tests/google-vertex-http.test.ts asserting diagnostic warning is emitted for location errors and suppressed for non-location errors.
    • Added unit test coverage in tests/error-fidelity.test.ts for permission_error / location_not_supported mapping and mixed-case input.

📝 Walkthrough

Walkthrough

The change adds shared detection for unsupported locations, maps matching errors to permission_error with location_not_supported, extends Google-specific classification, and logs routing diagnostics. Tests cover shared classification, Google formatting, and warning behavior.

Changes

Location restriction error handling

Layer / File(s) Summary
Shared permission error mapping
src/lib/errors.ts:130-144, src/lib/errors.ts:270-275, tests/server/error-fidelity.test.ts:3, tests/server/error-fidelity.test.ts:94-112
LOCATION_UNSUPPORTED_PATTERNS and isLocationUnsupportedMessage detect location, region, and country restrictions. classifyError maps matching messages and existing location_not_supported types to permission_error with code location_not_supported.
Google location detection and classification
src/adapters/google-errors.ts:2, src/adapters/google-errors.ts:58-67, tests/adapters/google/google-errors.test.ts:3, tests/adapters/google/google-errors.test.ts:90-111
Google error handling re-exports the shared detector and classifies matching messages as location-not-supported errors before rate-limit handling. Tests cover Antigravity and Vertex AI responses.
Google HTTP diagnostics
src/adapters/google-http.ts:2-7, src/adapters/google-http.ts:30-39, tests/adapters/google/google-vertex-http.test.ts:195-208, tests/adapters/google/google-vertex-http.test.ts:210-222
Final Google error formatting logs guidance about proxy or VPN TUN mode and IPv6/direct routing when the payload indicates an unsupported location. Tests verify both warning and non-warning cases.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 0226f

Google location-restriction responses are now reported as permission errors with a dedicated location_not_supported code and routing guidance, rather than invalid requests. Current coverage supports the intended classification and diagnostic behavior with no remaining merge-blocking risk.

설명

이 PR은 Google Antigravity(Cloud Code Assist)가 지역·IP 제한으로 요청을 거절할 때, OpenCodeX가 그 거절을 "잘못된 요청(invalid request)"으로 잘못 붙이던 문제를 고칩니다. 실제 업스트림 메시지는 대략 User location is not supported for the API use. 이고 HTTP 상태는 400, enum은 FAILED_PRECONDITION입니다. 그런데 지금 devsrc/adapters/google-errors.tsclassifyGoogle()은 400이거나 본문에 "invalid"가 보이면 곧바로 ${label} invalid request로 떨어집니다. 그래서 운영자·클라이언트가 "프롬프트나 JSON이 깨졌다"고 오해하기 쉽고, 다운스트림 OpenAI 호환 경로도 invalid_request_error로 번역해 버립니다. Codex CLI나 ChatGPT Desktop 같은 쪽은 그 타입을 영구적인 요청 문법 오류처럼 다루기 때문에, VPN·TUN·프록시·IPv6 누수를 점검하라는 힌트가 거의 나오지 않습니다.

지금 dev HEAD는 24c0409ae (#3465, Codex Set 머리줄 wrap + 진짜 Codex 마크)이고 패키지는 2.43.0입니다. Google 쪽 분류 골격은 그대로입니다. 쿼타 고갈 needle, 일시 rate limit 패턴, 401/403/503 분기는 이미 있고, 그 다음에 오는 400 범용 "invalid request" 버킷이 지역 거절까지 삼키는 구멍이 이 PR의 대상입니다. 이 변경은 (1) google-errors.ts에 위치/지역 문구 목록과 isGoogleLocationUnsupportedText를 넣고, 쿼타 판정 직후·400 범용 분기 전에 ${label} location not supported로 붙입니다. (2) src/lib/errors.tsclassifyError()isLocationUnsupportedMessage를 추가해 permission_error + code: "location_not_supported"로 올립니다. (3) google-http.tsnormalizeFinalGoogleError에서 같은 문구가 보이면 TUN/프록시/IPv6 누수를 점검하라는 console.warn을 남깁니다. (4) tests/google-errors.test.tstests/error-fidelity.test.ts에 단위 테스트를 붙입니다.

방향은 현재 dev의 에러 fidelity 습관과 잘 맞습니다. 쿼타·레이트리밋·인증·권한을 메시지 문구로 먼저 갈라 쓰는 패턴의 연장선이고, 클라이언트가 "고칠 수 있는 요청 오류"와 "네트워크·계정·지역 막힘"을 다르게 보이게 하려는 목적도 분명합니다. 이슈 #3467에 적힌 재현과 목표가 그대로 PR로 옮겨져 있고, Antigravity뿐 아니라 Vertex 라벨 경로도 같은 safeGoogleHttpErrorMessage를 타므로 테스트가 둘 다 검사하는 것도 타당합니다.

다만 운영·품질 쪽에서 몇 가지가 걸려 있습니다. 베이스가 main이라 제목에 [WRONG BRANCH]가 붙었고 draft이며, Enforce PR target branch / enforce-target가 FAILURE입니다. 리뷰 체크리스트 네 칸도 비어 있습니다. 그리고 바늘 문구 목록이 google-errors.tserrors.ts에 거의 같은 내용으로 두 벌입니다. 한쪽만 고치면 어긋날 수 있습니다. 특히 공통 꼬리 문구 not supported for the api use는 위치와 무관한 Google 거절문에도 걸릴 수 있어 범위가 넓습니다. 이슈 #3467은 이미 CLOSED 상태인데 PR 본문은 여전히 Fixes #3467을 가리킵니다. 닫힌 이유와 이 PR의 관계를 한 번 확인하는 편이 좋습니다.

src/adapters/google-errors.ts / GOOGLE_LOCATION_UNSUPPORTED_PATTERNS - not supported for the api use 한 줄만으로도 매칭된다. 위치·지역·국가 단어가 없는 다른 FAILED_PRECONDITION 거절도 location으로 잘못 붙을 수 있다.
src/lib/errors.ts / isLocationUnsupportedMessage - google-errors 쪽 목록과 내용이 거의 같은 두 번째 복사본이다. 나중에 한쪽만 고치면 classifyGoogle 라벨과 classifyError 코드가 어긋날 수 있다.
src/adapters/google-http.ts / normalizeFinalGoogleError console.warn - 요청마다 같은 지역 거절이 반복되면 콘솔이 같은 경고로 빠르게 차오른다. 운영 힌트로는 좋지만, 레이트 제한이나 한 줄 요약 로그가 없는 점은 알아둘 필요가 있다.
src/lib/errors.ts / classifyError 삽입 위치 - location 분기가 subscription_required 뒤, 일반 403 permission_denied 앞이다. 지역 거절이 403+권한 문구와 겹치면 location_not_supported가 이긴다. 의도에 맞는지 한 번만 확인하면 좋다.
PR base / enforce-target - 베이스가 main이라 dev 머지 트레인에 바로 넣을 수 없다. 체크리스트도 미완료·draft다.
이슈 #3467 - 이미 CLOSED인데 PR은 Fixes #3467이다. 닫힘과 이 수정 PR의 관계를 확인해야 한다.

메인테이너의 판단이 필요한 지점

  • not supported for the api use를 단독 needle로 둘지, location/region/country와 같이 나올 때만 잡을지
  • 바늘 목록을 한 모듈로 합칠지, 지금처럼 adapter/lib 이중 유지를 허용할지
  • 이슈 #3467이 이미 닫힌 상태에서 이 PR만 살려 dev로 리타겟할지
  • console.warn을 그대로 둘지, 구조화 로그·중복 억제로 바꿀지

너의 추천
베이스를 dev로 바꾸고(지금 main + WRONG BRANCH/draft), CI와 체크리스트를 맞춘 뒤 머지하세요. 머지 전에 not supported for the api use 단독 매칭은 좁히거나 location/region/country와 AND로 묶고, 가능하면 바늘 목록은 한곳으로 모으는 작은 후속 커밋을 권합니다. 내용 자체(invalid_request → permission/location)는 dev 방향과 맞고 테스트도 있어서, 브랜치·needle만 정리되면 넣을 가치가 있습니다.

Approved exact head e11089af85f8c1da4e67fe388b768d09078e8dcb.

I verified the revised implementation against current dev: the location matcher now requires an explicit location/region/country cue, the shared matcher removes the earlier adapter/lib drift, mixed-case input is normalized once, and the diagnostic warning has positive and negative adapter coverage. The error remains redacted and is classified as permission_error / location_not_supported instead of a request-syntax failure.

Local isolated verification with Bun 1.4.0:

  • 44 focused tests passed across google-errors, error-fidelity, and google-vertex-http
  • bun run typecheck passed
  • bun run privacy:scan passed
  • protected local runtime configuration hashes remained unchanged

The exact-head Cross-platform CI and service checks are also green. This is ready for the normal dev merge path.

All reviewer feedback has been addressed and verified:

  1. Target branch was cleanly retargeted to dev with all checks passing.
  2. The location pattern matching in src/adapters/google-errors.ts was constrained and deduplicated with src/lib/errors.ts to prevent false positives.
  3. Diagnostic logging warning for location-unsupported errors was added and verified with dedicated test coverage in tests/google-vertex-http.test.ts.
  4. Full cross-platform CI matrix and CodeRabbit checks are completely green (15/15 successful runs), and the PR is marked review-ready.

Rebased cleanly on latest dev (a594a7f21), resolving the test layout merge conflict in tests/server/error-fidelity.test.ts. All 44 tests pass locally and the branch is conflict-free and mergeable.

Re-approved exact rebased head 0226f612f.

I compared it against the previously approved e11089af8 with git range-diff. The implementation and regression semantics are unchanged; the only material rebase adaptation is the already-landed test-layout move into tests/adapters/google/* and tests/server/error-fidelity.test.ts. The constrained location/region/country matcher, shared classification helper, redacted diagnostic warning, and positive/negative coverage remain intact.

Please wait for the newly started exact-head CI to finish green before merge. Any further head change needs incremental review.

Carried into dev by #3608 at c44e187, with original attribution retained and the concrete follow-up corrections described there. Closing the source PR as superseded. Final dev HEAD CI is still pending under the owner-authorized admin-merge workflow; this closure does not claim CI success.
