Question

我正在尝试在aws上执行lambda以列出我的认知用户池中的用户。这是我在nodejs中的代码：

  const queryStringParameters = event.queryStringParameters;
  var paginationToken = '';
  if ( queryStringParameters && queryStringParameters.paginationToken ) {
    paginationToken = queryStringParameters.paginationToken;
  }
  var limit = '10';
  if ( queryStringParameters && queryStringParameters.limit ) {
    limit = queryStringParameters.limit;
  }

  var params = {};
  if ( paginationToken != '' ) {
    params = {
      UserPoolId: userPoolId, /* required */
      //Filter: 'STRING_VALUE',
      Limit: limit,
      PaginationToken: paginationToken
    };
  } else {
    params = {
      UserPoolId: userPoolId, /* required */
      //Filter: 'STRING_VALUE',
      Limit: limit,
      PaginationToken: paginationToken
    };
  }

  cognitoidentityserviceprovider.listUsers(params, function (err, data) {
    if (err) {
      response.code = "ERROR"
      response.message = "Han ocurrido errores"
      response.result = err
      callback(null, {
        statusCode: 500,
        headers,
        body: JSON.stringify(response)
      })
    }
    response.code = "OK"
    response.message = ""
    response.result = data
    callback(null, {
      statusCode: 200,
      headers,
      body: JSON.stringify(response)
    });
  });

我正在邮递员上使用在其他调用中返回的paginationToken测试此lambda。返回此错误。
