azapi_resource_action:“str”参数的值无效:需要字符串

我使用azapi_resource_action生成密钥,代码如下

resource "azapi_resource_action" "ssh_public_key_gen" {
  type        = "Microsoft.Compute/sshPublicKeys@2022-11-01"
  resource_id = azapi_resource.ssh_public_key.id
  action      = "generateKeyPair"
  method      = "POST"

  response_export_values = ["publicKey", "privateKey"]
}

当试图显示公钥时,我得到以下错误

output "key_data" {
  value = jsondecode(azapi_resource_action.ssh_public_key_gen.output).publicKey
}




 Error: Invalid function argument

│   on ssh.tf line 23, in output "key_data":
│   23:   value = jsondecode(azapi_resource_action.ssh_public_key_gen.output).publicKey
│     ├────────────────
│     │ azapi_resource_action.ssh_public_key_gen.output is object with 2 attributes

我正在使用以下提供程序版本

  required_providers {
    azapi = {
      source  = "azure/azapi"
      version = "~>1.5"
    }
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "~>3.0"
    }
}
