步骤1: 确保lambda函数已添加正确的EventBridge触发器：步骤包括创建一个lambda函数以及添加一个EventBridge触发器

// 创建lambda函数
exports.handler = async (event, context) => {
  console.log(event);
  return {
    statusCode: 200,
    body: JSON.stringify('Hello from Lambda!'),
  };
};

// 添加EventBridge触发器
{
  "source": [
    "aws.ec2"
  ],
  "detail-type": [
    "EC2 Instance State-change Notification"
  ],
  "detail": {
    "state": [
      "running"
    ]
  }
}

步骤2: 确保有适当的权限：为您的lambda函数添加相应的权限

{
  "Statement": [
    {
      "Action": [
        "logs:CreateLogGroup",
        "logs:CreateLogStream",
        "logs:PutLogEvents"
      ],
      "Effect": "Allow",
      "Resource": "arn:aws:logs:*:*:*"
    }
  ],
  "Version": "2012-10-17"
}

步骤3: 确保事件规则适用于lambda函数的范围：

{
  "Statement": [
    {
      // 添加lambda函数的arn
      "Resource": "arn:aws:lambda:us-west-2:1XXXXX:function:my-lambda-function",
      "Effect": "Allow",
      "Action": [
        "lambda:InvokeFunction"
      ]
    }
  ],
  "Version": "2012-10-17"
}

这些步骤将确保AWS EventBridge事件在具有适当权限的lambda函数中正确触发。
