子网ID“ aws_subnet.firstsubnet.id”不存在，状态码：400，

如何解决子网ID“ aws_subnet.firstsubnet.id”不存在，状态码：400，

我想使用AWS Auto Scaling组（ASG）。 如何纠正错误？ 错误：创建AutoScaling组时出错：ValidationError：子网ID'aws_subnet.firstsubnet.id'不存在 状态码：400，请求ID：06571fdb-585b-486e-ae9c-19d3acb14d9e

解决方法

出现此错误的原因是您传递了strings而不是实际的子网ID。

因此，而不是：

vpc_zone_identifier       = ["aws_subnet.firstsubnet.id","aws_subnet.secondsubnet.id"]

应该是：

vpc_zone_identifier       = [aws_subnet.firstsubnet.id,aws_subnet.secondsubnet.id]

或

vpc_zone_identifier       = ["${aws_subnet.firstsubnet.id}","${aws_subnet.secondsubnet.id}"]
