MongoDB:未在数据库上授权执行命令eval

这是我正在运行的查询:

db.surveyquestion.copyTo('surveyquestionV2')

我收到的错误:

{
    "message" : "MongoError: not authorized on GenericSurveyTool to execute command { $eval: function (collName, newName) {\r" +
              "var from = db[collName];\r" +
              "..., args: [ 'surveyquestion', 'surveyquestionV2' ], $db: 'GenericSurveyTool' }",
    "stack" : "script:1:19",
    "code" : 13
}

用于运行此查询的admin db中的我的用户:

query:  db.getUsers();


/* 2 */
{
    "_id" : "admin.moiz",
    "user" : "moiz",
    "db" : "admin",
    "roles" : [
        {
            "role" : "root",
            "db" : "admin"
        }
    ]
}

此用户具有root角色,但仍无法复制集合。请帮忙!!
