在MongoDB nuget包上使用ELMAH 配置日志到MongoDB后,它成功登录到MongoDB集合,但在尝试访问Web界面时,它给出了以下异常:

命令'create'失败:集合'collectionname'已经存在(响应:{"note":"autoIndexId选项已弃用,将在以后的版本中删除","ok":0.0,"errmsg":"一个集合'collectionname'已存在","code":48,"codeName":"NamespaceExists"})

我不知道为什么每次尝试为elmah创建web配置配置集合时:

 <sectionGroup name="elmah">
      <section name="security" requirePermission="false" type="Elmah.SecuritySectionHandler, Elmah" />
      <section name="errorLog" requirePermission="false" type="Elmah.FallbackErrorLogSectionHandler, Elmah.FallbackErrorLog" />
      <section name="errorMail" requirePermission="false" type="Elmah.ErrorMailSectionHandler, Elmah" />
      <section name="errorFilter" requirePermission="false" type="Elmah.ErrorFilterSectionHandler, Elmah" />
    <!--<section name="errorLog" requirePermission="false" type="Elmah.ErrorLogSectionHandler, Elmah" />-->
  </sectionGroup>
