透過自動化建立失敗警示 EventBridge

Amazon Chime 開發套件會在叫用您的處理器 Lambda 函數時發生錯誤時傳遞事件。無論處理器在建立通道流時指定的Fallback動作為何，都會傳送事件。您可以撰寫簡單的規則來指定這些事件，再加上當任何事件符合規則時要採取的自動化動作。如需詳細資訊，請參閱 Amazon EventBridge 使用者指南。發生類似這些錯誤時，視您設定的Fallback動作而定，通道上的成員無法傳送訊息，否則訊息會在不進行處理的情況下透過通道流動。如需有關此Fallback動作的詳細資訊，請參閱 Amazon Chime 開發套件 API 參考資料Processor中的。

此範例顯示典型的失敗事件。
