Terraform 销毁在删除依赖资源之前删除提供程序

问：

背景： 我正在努力销毁 AWS 中包含跨域依赖项的功能分支（us-west-2 部署依赖项对 us-east-1 资源）该项目依赖于本地区域 SQS 队列的 SNS 主题订阅，因此我添加了一个 us-east-1 提供程序以允许部署完成而不会出错。

问题： 当不再需要功能分支时，我想对创建的 AWS 资源（lambda、queue 和 east-1 主题订阅）执行 terraform 销毁，但 tf 错误并出现以下错误：

│ Error: Provider configuration not present
│ 
│ To work with aws_sns_topic_subscription.els_event_subscription (orphan) its
│ original provider configuration at
│ provider["registry.terraform.io/hashicorp/aws"].sns2sqs is required, but it
│ has been removed. This occurs when a provider configuration is removed
│ while objects created by that provider still exist in the state. Re-add the
│ provider configuration to destroy
│ aws_sns_topic_subscription.els_event_subscription (orphan), after which you
│ can remove the provider configuration again.

terraform 代码

provider "aws" {
  alias  = "sns2sqs"
  region = "us-east-1"

    default_tags {
        tags = {
          "<some-tags>" = ""
        }
    }

    ignore_tags {
        key_prefixes = ["<some_prefix>"]
    }
}

# The failing topic subscription
resource "aws_sns_topic_subscription" "els_event_subscription" {
  provider               =  aws.sns2sqs
  topic_arn              = "${var.environment}" == "prod" ? "${var.els_sns_topics["prod"]}" : "${var.els_sns_topics["dev"]}"
  protocol               = "sqs"
  endpoint               = "${some-endpoint.arn}"
  endpoint_auto_confirms = true
  filter_policy          = jsonencode(var.event_filter_policy)
}
