nodent fails to parse js file

[Antender]

The isolated pattern which led to crash:

if (await myAsyncFunction(args)) {
} else {
}

Notice, that else clause is empty

Output at startup:

Works me for: http://nodent.mailed.me.uk/#if%20(await%20myAsyncFunction(args))%20%7B%0A%7D%20else%20%7B%0A%7D%0A

Can you provide more details? Nodent version? Maybe a larger code sample?

My nodent version is 2.5.0, but when i paste this code snippet in the web version it displays the problem:

async function StartTournament() {
    if (await redisClient.get("lock") == null) {
        await redisClient.set("lock", "")
        await redisClient.incr("tournamentid")
        await redisClient.del("boosts")
        var playerAmount = await redisClient.zcard("scores:current")
        var index = 1
        var cursor = 0
        do {
            var result = await redisClient.zscan("scores:current", cursor)
            var profile_index = 0
            var score_index = 1
            while (profile_index < result[1].length) {
                var profile_id = result[1][profile_index]
                var score = result[1][score_index]
                var percent = index * 100.0 / playerAmount
                var reward = null
                if (percent >= (100 - 1)) {
                    await redisClient.hset("boosts", profile_id, "gold")
                    await redisClient.hincrby("top_reached", profile_id, 1)
                    reward = settings.rewards[0] //3 items
                } else if (percent >= (100 - 2)) {
                    await redisClient.hset("boosts", profile_id, "silver")
                    reward = settings.rewards[1] //3 items
                } else if (percent >= (100 - 15)) {
                    await redisClient.hset("boosts", profile_id, "bronze")
                    reward = settings.rewards[2] //3 items
                } else if (percent >= (100 - 30)) {
                    reward = settings.rewards[3] //crystals
                } else if (percent >= (100 - 50)) {
                    reward = settings.rewards[4] //coins
                }
                var topReached = await redisClient.hget("top_reached", profile_id)
                var alltimeScore = await redisClient.zscore("scores:alltime", profile_id)
                var stars = await redisClient.hget("stars", profile_id)
                var unclaimedRewardsRes = await StatsfindOne({ 'profile_id': profile_id }, 'unclaimedRewards')
                var unclaimedRewards = null
                if (unclaimedRewardsRes != null) {
                    unclaimedRewards = unclaimedRewardsRes.unclaimedRewards
                    await StatsModel.findOneAndUpdate(
                        { 'profile_id': profile_id },
                        {
                            "$set":
                            {
                                "topReached": (topReached == null ? 0 : topReached),
                                "alltimeScore": (alltimeScore == null ? 0 : alltimeScore),
                                "stars": (stars == null ? 0 : stars),
                                "unclaimedRewards": ((reward == null) ? unclaimedRewards : unclaimedRewards.concat(reward))
                            }
                        })
                } else {
                    await StatsModel.create(
                        {
                            'profile_id': profile_id,
                            'topReached': (topReached == null ? 0 : topReached),
                            'alltimeScore': (alltimeScore == null ? 0 : alltimeScore),
                            'stars': (stars == null ? 0 : stars),
                            'unclaimedRewards': []
                        })
                }
                profile_index += 2
                score_index += 2
                index++
            }
            cursor = result[0]
        } while (cursor != 0)
        await redisClient.del("scores:current")
        await redisClient.del("last_played")
        await redisClient.set("started", (Date.now() + tournamentDuration).toString())
        await redisClient.del("stopped")
        await redisClient.del("lock")
    } else {

    }
}

After adding console.log("locked") into the last else everything seems to be working fine

Thanks for the snippet. I'm away for a couple of weeks, but will have a look when I return. If you find a work-around in the meanwhile, please post it too as it may help me spot the bug
