尝试通过terraform解析json输入文件

我对terraform非常陌生,正在尝试理解它。我正在尝试解析一个示例json文件,并尝试显示键和值。到目前为止,我已经完成了以下操作,但不起作用。任何帮助都将不胜感激。

example.json :

{
    "Clients":[
        {
            "alias": "XXX-ED",
            "name": "XXX-ED | XXX Cloud | Dev/Test",
            "prefix": "xxxed",
            "id": 12345,
            "cluster": 3,
            "ZoneName": "East US 2",
            "EnvironmentName": "Dev/Test",
            "AzureSubscriptionID": "xxxxxx-xxxx-xxxxx-xxxx-xxxxxx",
            "AzureDirectory": "xxxxxx.onmicrosoft.com",
            "AzureTenantID": "xxxxxx-xxxx-xxxxx-xxxx-xxxxxx"
        },
        {
            "alias": "XXX-EM",
            "name": "XXX-EM | XXX Cloud | Management",
            "prefix": "xxxem",
            "id": null,
            "cluster": null,
            "ZoneName": "East US 2",
            "EnvironmentName": "Management",
            "AzureSubscriptionID": "xxxxxx-xxxx-xxxxx-xxxx-xxxxxx",
            "AzureDirectory": "xxxxxx.onmicrosoft.com",
            "AzureTenantID": "xxxxxx-xxxx-xxxxx-xxxx-xxxxxx"
        }
    ]
}

地形代码

data "local_file" "input"{
  filename = "${path.module}/example.json"
}

locals {
  raw_json_object = jsondecode(data.local_file.input.content)
  root_node       = flatten(local.raw_json_object["Clients"])
  
  expected_output = [
    for clients in local.root_node :[
      for key in clients:
        key.AzureDirectory
      ]
    ]
  }
}

output "raw_content" {
  value = local.expected_output
}

获取以下错误

计划失败。Terraform在生成此计划时遇到错误。错误:main.tf第38行上不支持的属性,在locals:38:key中。AzureDirectory 无法访问基元类型值(字符串)上的属性。
