var successPlayers;
var failedPlayers;
var logPath = './test/server_log.txt'(async () => {
  allStat = await ServerLogPlayerData(logPath);
  stats = await Promise.all(allStat)
    .then(r => r)
    .catch(e => e);
  // Filter players in case some requests failed to retry later
  successPlayers = _.filter(stats, s => !_.hasIn(s, 'error'));
  failedPlayers = _.difference(stats, successPlayers);

  console.log(_.map(successPlayers, s => s.data()));

  console.log('FAILED: ');
  console.log(failedPlayers);
});
