Terraform 尝试传递aws_secretsmanager_secret_版本值时出错

在RDS AWS创建的密码部分，我试图传递

AWS\u secretsmanager\u secret\u version

值。我正在犯错误

资源“aws\u secretsmanager\u secret”“secret”{

kms_key_id=“${data.aws_kms_key.sm.arn}”
name=“气流”
}
资源“随机字符串”“rds\U密码”{
长度=16
特殊=真实
覆盖_special=“/@”
}
资源“aws\u secretsmanager\u secret\u版本”“secret”{
secret_id=“${aws_secretsmanager_secret.secret.id}”
secret_string=正如您在key val中看到的，secret_string中的对象应该被注入jsonencode（）

请看以下示例（改编自文档页面）：

我认为您没有正确索引地图。问题在于
secret\u string][“rds\u password”]

替换

password = "${jsondecode(aws_secretsmanager_secret_version.secret.secret_string)["rds_password"]}"

与

不能在变量块中添加动态变量。对，这不起作用。
password = "${jsondecode(aws_secretsmanager_secret_version.secret.secret_string)["rds_password"]}"

password = "${jsondecode(aws_secretsmanager_secret_version.secret.secret_string["rds_password"])}"
