根因分析

S3 存储桶未配置事件通知以调用 Lambda 函数，通常是由于手动删除了通知或存储桶策略不正确。

English

The S3 bucket does not have an event notification configured to invoke the Lambda function, often due to manual deletion of the notification or incorrect bucket policy.

解决方案

  1. Use AWS CLI to add the event notification: `aws s3api put-bucket-notification-configuration --bucket my-bucket --notification-configuration file://config.json` where config.json contains: `{"LambdaFunctionConfigurations": [{"LambdaFunctionArn": "arn:aws:lambda:us-east-1:123456789012:function:my-function", "Events": ["s3:ObjectCreated:*"]}]}`
  2. Check and update the Lambda resource-based policy to allow S3 invoke: `aws lambda add-permission --function-name my-function --statement-id s3-invoke --action lambda:InvokeFunction --principal s3.amazonaws.com --source-arn arn:aws:s3:::my-bucket`

无效尝试

常见但无效的做法:

  1. 50% 失败

    The console may not create the notification if the bucket already has a notification limit (max 100) or if permissions are insufficient.

  2. 80% 失败

    The bucket policy is independent of event notifications; the notification itself must be configured via S3 API.
