在运行木偶期间，节点上的事件查看器出现以下错误。我怀疑问题出在我的个人资料中的查询功能不正确。

Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Resource Statement,Scconfig::Coserveradmin[SomeSettings]:
parameter 'parameterA' expects a String value,got Undef
parameter 'parameterB' expects a String value,got Undef
parameter 'parameterC' expects a String value,got Undef
parameter 'parameterD' expects a String value,got Undef

coserveradmin是具有所有字符串参数的define资源。我想从Json文件中查找值

{
    "SASettings" : {
        "Watchdog" : {
            "ParameterA"            : "somevalue","ParameterB"            : "somevalue"
        },"Serversettings" : {
            "ParameterC"            : "somevalue","ParameterD"            : "somevalue",},"GeneralSettings" : {
            "ParameterE"            : "somevalue","ParameterF"            : "somevalue","customsettings_prod" : {
            "ParameterG"            :"somevalue","ParameterH"            : "%{facts.hostname}.example-cloud.com"
        },"customsettings_dev" : {
            "ParameterI"            :"","ParameterK"            : "%{facts.hostname}.example.net"
        }
    }
}

在我的hiera.yaml文件中，我定义了json文件的名称和路径。

- name: "Desired Some Settings"
    path: "default/serveradmin.json" 

在个人资料中，我有以下代码。

    class profile::scconfig_someprofile_a {
                .
                .
                .
                $hname= $::facts['hostname']
                $mac= "${facts['macaddress'].delete(':')}"
                $adminpropeties = lookup('SASettings')

               if $hname=~someregex {
                           scconfig::coserveradmin{ 'SomeSettings':
                           property1 => $adminpropeties['customsettings_prod.ParameterG'],property2 => $adminproperties['Watchdog.ParameterA'],property3 => $adminproperties['Watchdog.ParameterB'],property4 => $adminproperties['Serversettings.ParameterC'],.
                           .
                           .
                           .
                           and so on
                           .
                           macaddress => $mac,}
               elsif $hname=~someregex {
                           scconfig::coserveradmin{ 'SomeSettings':
                           property1 => $adminpropeties['customsettings_dev.ParameterI'],}

还根据要求添加“定义”资源的代码。

define scconfig::coserveradmin(
    String $Property1,String $Property2,String $Property3,String $Property4,.
    .
    .
    String $macaddress,) {

  $dscmoduleversion = lookup('requires.modules.codsc.version')
  if $dscmoduleversion != '' {
      $module = {
          'name'    => 'codsc','version' => $dscmoduleversion,}
  }else{
      $module = 'codsc'
  }

  $configname1='someconfig1'
  $configname2='someconfig2'
  $configname3='someconfig3'

  dsc { 'someconfig1':
    require       => lookup('requires.cloudopssoftware'),resource_name => 'Someresourcename',module        => $module,properties    => {
      configname         => $configname1,Prop1   => $Property1,Prop2   => $Property2,Prop3   =>$Property3,}
  dsc { 'someconfig2':
   require       => lookup('requires.cloudopssoftware'),resource_name => 'someresourcename2',properties    => {
      configname    => $configname2,Prop1   => $Property4,Prop2   => $Property5,Prop3   =>$Property6,}

 dsc { 'someconfig3':
   require       => lookup('requires.cloudopssoftware'),resource_name => 'someresourcename3',properties    => {
      configname    => $configname3,Prop1   => $Property6,Prop2   => $Property7,Prop3   =>$Property8,.
            .
            .
            Propn   => $macaddress
         },}

请注意，最后一个属性即macaddress是在配置文件类中评估的，因此我看不到任何错误。

任何想法可能是什么问题。
