我有一个地形代码如下

locals {
    file_path = format("%s-%s", var.test1, var.test2)
    test_decode  =  yamldecode((data.github_repository_file.test.content))
   }
    data "github_repository_file" "test" {
     repository = "test-repo"
     branch     = "develop"
    file       = "${local.file_path}/local/test.yaml"
    }
  test_encode = ${yamlencode(local.test_decode.spec.names)}

当test.yaml文件中存在“.spec.names”属性时，此功能正常工作。由于我们根据local.file_path选择test.yaml，因此有时属性.spec.names可能不存在于test.yaml中，计划失败，并显示**“错误：不支持的属性”“。如何检查test.yaml中存在的“.spec.names**”属性？
更新问题以添加yaml示例

带名称属性的Yaml

apiVersion: helm.toolkit.gitops.io/v2beta1
kind: HelmRelease
metadata:
  name: "test"
  namespace: "test-system"
spec:
  chart:
    spec:
      chart: "test-environment"
      version: "0.1.10"
  names:
    key1: "value1"
    key2: "value2"
    key3: "value3"
    key4: "value4"

没有名称属性的YAML

apiVersion: helm.toolkit.gitops.io/v2beta1
kind: HelmRelease
metadata:
  name: "test"
  namespace: "test-system"
spec:
  chart:
    spec:
      chart: "test-environment"
      version: "0.1.10"
