从社区连接器向用户抛出错误

我跟随导游在 https://developers.google.com/datastudio/connector/error-handling#non-admin-messages 用于从getData方法向用户返回错误。然而,即使使用提供的示例方法向用户抛出错误,我仍然会在所有报告中得到一般错误:

记录方法:

/**
   * Throws an error that complies with the community connector spec.
   * @param {string} message The error message.
   * @param {boolean} userSafe Determines whether this message is safe to show
   *     to non-admin users of the connector. true to show the message, false
   *     otherwise. false by default.
   */
  function throwConnectorError(message, userSafe) {
    userSafe = (typeof userSafe !== 'undefined' &&
                typeof userSafe === 'boolean') ?  userSafe : false;
    if (userSafe) {
      message = 'DS_USER:' + message;
    }

    throw new Error(message);
  }

呼叫代码:

try{
    //SOME CODE HERE THAT THROWS ERROR
}catch (ex){
    logConnectorError("getData: Unexpected Error:", ex);
    if (ex.message !== null){    
      throwConnectorError("Unable to fetch data due to server error: " + ex.message, true);
    }
    else{
      throwConnectorError("Unexpected error: " + ex, true);
    }
  }

运行时出错:

Error Details

这个系统是否仍在工作,或者是否有一个示例工作连接器,我可以查看它,看看是否有我遗漏的东西?
