由于连接器错误，提交凭证失败。

Question

我第一次尝试建立自己的连接器。我得到了以下错误。

Sorry, we failed to submit your credentials because there was an error in the connector in processing the credentials.

这是我目前的代码

function getAuthType() {
  var cc = DataStudioApp.createCommunityConnector();
  return cc.newAuthTypeResponse()
    .setAuthType(cc.AuthType.USER_TOKEN)
    .setHelpUrl('https://api-doc-help-url/authentication')
    .build();
}


function validateCredentials(userName, token) {
  var rawResponse = UrlFetchApp.fetch('https://api/v2/stuff/' + userName , {
    method: 'GET',
    headers: {
    'Authorization': userName + ':' + token
    },
    muteHttpExceptions: true
  });

  return rawResponse.getResponseCode() === 200;
}

function isAuthValid() {
  var userProperties = PropertiesService.getUserProperties();
  var userName = userProperties.getProperty('dscc.username');
  var token = userProperties.getProperty('dscc.token');

  return validateCredentials(userName, token);
}

function setCredentials(request) {
  var creds = request.userToken;
  var username = creds.username;
  var token = creds.token;

  var validCreds = checkForValidCreds(username, token);
  if (!validCreds) {
    return {
      errorCode: 'INVALID_CREDENTIALS'
    };
  }
  var userProperties = PropertiesService.getUserProperties();
  userProperties.setProperty('dscc.username', username);
  userProperties.setProperty('dscc.token', token);
  return {
    errorCode: 'NONE'
  };
}

我不知道这一切是如何工作的。我知道，我需要在头中传递授权，其值如下所示 userName:token

当部署我的清单并点击Google Data Studio链接时，我被重定向到选择连接器数据工作室界面。当我试图提交Usernam和Token时，出现了错误。

checkForValidCreds没有在函数setCredentials中定义。
