错误:不支持的属性，each.value是具有2个属性的对象

Question

我正在尝试使用for_each和locals创建多个网络接口，这是我的代码

locals {
network_interfaces = {
a = {
subnet_id      = module.vpc.public_subnets[0],
security_group = [aws_security_group.ssh.id],
},
b = {
subnet_id       = module.vpc.public_subnets[0],
security_groups = [aws_security_group.ssh.id],
},
c = {
subnet_id       = module.vpc.public_subnets[1],
security_groups = [aws_security_group.ssh.id],
},
d = {
subnet_id       = module.vpc.public_subnets[1],
security_groups = [aws_security_group.ssh.id],
},
}
}

在这里，我试图用for_each迭代local.network_interfaces，这样我就可以创建4个网络接口

resource "aws_network_interface" "this" {
for_each  = local.network_interfaces
subnet_id = each.value.subnet_id
security_groups = each.value.security_groups
tags = {
Name = "${each.key}_network_interface"
}
}

但是当我运行Terraform应用程序时，它会给我这个错误

│ Error: Unsupported attribute
│ 
│   on main.tf line 61, in resource "aws_network_interface" "this":
│   61:   security_groups = each.value.security_groups
│     ├────────────────
│     │ each.value is object with 2 attributes
│ 
│ This object does not have an attribute named "security_groups"

如有任何帮助，将不胜感激

map和a密钥的值中安全组对应的object密钥需要与映射中其他object值中的密钥匹配：

a = {
subnet_id       = module.vpc.public_subnets[0],
security_groups = [aws_security_group.ssh.id],
},
