Terraform调用aws-cli时发生外部数据错误

Question

尝试将aws cli调用作为terraformexternal data运行，但unmarshal string出现错误

Terraform:

data "external" "cognito" {
program = ["sh", "-c", "aws cognito-idp list-user-pool-clients --user-pool-id eu-west-xxx | jq '.UserPoolClients | .[] | select(.ClientName | contains("AmazonOpenSearchService")) | .ClientId'"] 
}

直接从bash运行命令返回：

"123456"

通过地形错误：

│ The data source received unexpected results after executing the program.
│ 
│ Program output must be a JSON encoded map of string keys and string values.
│ 
│ If the error is unclear, the output can be viewed by enabling Terraform's logging at TRACE level. Terraform documentation on logging: https://www.terraform.io/internals/debugging

当使用Terraform外部数据源运行临时脚本时，您需要返回一个有效的json对象(文档中还提到了字符串的映射(，而"123456"不是。你需要'{"clientId":"123456"}'之类的东西。
