Google App-Script通过服务调用功能

Question

使用服务帐户从java代码访问google appScript上的功能时出现错误：

Exception in thread "main" com.google.api.client.googleapis.json.GoogleJsonResponseException: 500 Internal Server Error
{
  "code" : 500,
  "errors" : [ {
    "domain" : "global",
    "message" : "Internal error encountered.",
    "reason" : "backendError"
  } ],
  "message" : "Internal error encountered.",
  "status" : "INTERNAL"
}

同样的情况发生在具有默认凭据的app-engine
