void errorは意図的な抑制であり、行 47 のコメントがその理由を示します。ただし SonarCloud はこれを failure として報告するため、品質ゲートを止める可能性があります。optional catch binding を使うと、変数を導入せずに同じ意図を表せます。
♻️ 代替案

In `@durable-objects/tokenizer-controller/src/index.ts`:
- Around line 1-3: estimator.ts のトップレベル await がルート実行時 import で WASM
を初期化しないよう、index.ts から estimator の再エクスポートを外し、contracts
専用の公開サブパスを追加してください。契約の定数やパーサーを実行時に利用する消費者はその contracts サブパスを参照し、型のみの利用では import
type を維持してください。
In `@durable-objects/tokenizer-controller/src/observation.ts`:
- Around line 46-49: Update the catch block surrounding the telemetry operation
in observation.ts to use an optional catch binding instead of declaring error
and suppressing it with void error. Preserve the existing behavior that
telemetry failures are ignored and never propagate into tokenization.
In `@durable-objects/tokenizer-controller/test/contracts.test.ts`:
- Around line 36-62: Extend the boundary tests for parseTokenizeRequest to use
the multibyte character “あ” for both inputText and requestId, with character
counts that remain within the limits while UTF-8 byte counts exceed
MAX_INPUT_TEXT_BYTES or MAX_REQUEST_ID_BYTES; assert that both cases throw
TypeError.
In `@durable-objects/tokenizer-controller/test/estimator.test.ts`:
- Around line 96-155: Consolidate the four repeated work-limit tests around
TokenizerEstimator into one it.each table containing each case’s name and
inputText. Keep the shared encoder-call counter, rejection assertion, expected
error message, and zero-call assertion unchanged, while preserving all four
existing inputs.
- Around line 13-17: Update the fallback-path tests using contextFor so they
pass a shared events array and verify the telemetry emitted by
conservativeEstimateWithFallback. Assert outcome is fallback and validate
failureCategory, byteCount, and estimationPath for each relevant fallback
scenario.
In `@durable-objects/tokenizer-controller/test/observation.test.ts`:
- Around line 70-84: Update the test around emitTokenizerStage to assert the
emitted start-phase log payload, verifying that durationMs and outcome are
omitted while the supported event fields remain present; keep the existing
one-call assertion and parameterized stages intact.
In `@durable-objects/tokenizer-controller/test/tokenizer-controller.test.ts`:
- Around line 21-56: トークン化 RPC の不正リクエスト挙動を検証するテストを追加してください。既存の controller と
validRequest を使い、messageCount などの検証失敗する値を渡して tokenize が型付き結果を返さず TypeError として
reject されることを確認し、Gateway の unavailable 変換前提を維持してください。
