我正在尝试在CFT中运行this yaml file来还原RDS快照。 运行堆栈时出现以下错误：
1 validation error detected: Value '[]' at 'alarmActions' failed to satisfy
constraint: Member must satisfy constraint: [Member must have length less than or
equal to 1024, Member must have length greater than or equal to 1]
(Service: AmazonCloudWatch; Status Code: 400; Error Code:
