根因分析

S3事件通知中指定的Lambda函数不存在或已被删除，导致通知配置验证失败。

English

The Lambda function specified in the S3 event notification does not exist or has been deleted, causing the notification configuration to fail validation.

解决方案

  1. Verify the Lambda function exists: `aws lambda get-function --function-name my-function`. If it exists, get its ARN: `aws lambda get-function-configuration --function-name my-function --query FunctionArn`. Then update the S3 notification with the correct ARN: `aws s3api put-bucket-notification-configuration --bucket my-bucket --notification-configuration file://notification.json` where notification.json contains the correct Lambda ARN.
  2. If the function was deleted, recreate it with the same name and ARN. Or update the notification to point to a different existing function.

无效尝试

常见但无效的做法:

  1. Recreate the S3 bucket and re-add notification 90% 失败

    The bucket is not the issue; the Lambda function ARN is invalid. Recreating the bucket is unnecessary.

  2. Update the Lambda function with the same name 70% 失败

    The function may need a different ARN format (e.g., including alias or version). Simply updating does not fix the ARN mismatch.
