RangeError: Maximum call stack size exceeded

[Ezcha]

I don't know if this is my code or the scaffold's code, butmost of the time when I execute the script below I get a "RangeError: Maximum call stack size exceeded" error. It works occasionally.

console.log("Mine plugin started.");
var mineflayer = require('mineflayer');
var scaffoldPlugin = require('mineflayer-scaffold')(mineflayer);
var vec3 = mineflayer.vec3;
module.exports.inject = inject;

function inject(bot) {

bot.on('whisper', function (username, message) {
    if (username == bot.username) return;
    if (message == 'mine') {
  bot.findBlock({
    point: bot.entity.position,
    matching: 56,
    maxDistance: 256,
    count: 1,
  }, function(err, blockPoints) {
    if (err) {
      console.log('Error trying to find Diamond Ore: ' + err);
    }
    if (blockPoints.length) {
      console.log('I found a Diamond Ore block at ' + blockPoints[0] + '.');
        var tempVar = vec3(blockPoints[0].position.x, blockPoints[0].position.y, blockPoints[0].position.z);
        bot.scaffold.to(tempVar);
    } else {
      console.log("I couldn't find any Diamond Ore blocks within 64.");
    }
  });
    }
});
}

Pretty sure the problem doesn't come from mineflayer-scaffold. You should use https://github.com/Darthfett/mineflayer-blockfinder and not the (very basic) findBlock embedded in mineflayer.

I thought about, changed it, but I am still getting the error. https://gyazo.com/cecfb65e961751a761cb52a0ff61311f

console.log("Mine plugin started.");
var mineflayer = require('mineflayer');
var scaffoldPlugin = require('mineflayer-scaffold')(mineflayer);
var vec3 = mineflayer.vec3;
module.exports.inject = inject;

function inject(bot) {

bot.on('whisper', function (username, message) {
    if (username == bot.username) return;
    if (message == 'mine') {
  bot.findBlock({
    point: bot.entity.position,
    matching: 56,
    maxDistance: 256,
    count: 1,
  }, function(err, blockPoints) {
    if (err) {
      console.log('Error trying to find Diamond Ore: ' + err);
    }
    if (blockPoints.length) {
      console.log('I found a Diamond Ore block at ' + blockPoints[0].position + '.');
        var tempVar = blockPoints[0].position
        bot.scaffold.to(tempVar);
    } else {
      console.log("I couldn't find any Diamond Ore blocks within 64.");
    }
  });
    }
});
}

Help? Most of the time my simple code doesn't run!

Getting the same problem. Code:

var mineflayer = require('mineflayer');
var navigatePlugin = require('mineflayer-navigate')(mineflayer);
var scaffoldPlugin = require('mineflayer-scaffold')(mineflayer);

var bot = mineflayer.createBot({
  host: "localhost",
  port: 25565,
  username: "Notch"
});

navigatePlugin(bot);
scaffoldPlugin(bot);

bot.on('chat', function(username, message) {
  if (username === bot.username) return;
  if (message.match(/^!echo .*/)) {
    bot.chat(message.substring(6));
  } else if (message.match(/^!come$/)) {
    bot.scaffold.to(bot.players[username].entity.position, function(err) {
      if (err) {
        bot.chat("didn't make it: " + err.code);
      } else {
        bot.chat("made it!");
      }
    })
  }
});

Every now and then it makes it the whole way... but most of the time it crashes. Here is the log.

A quick fix would be to add the --stack-size=value parameter when running node

node --stack-size=6000 file.js

You might need to adjust the 6000

[perryprog]

Ah this is a bummer 😕

It seems that the project is on my old laptop. I do remember trying to increase the stack size, to no success. I might try getting mineflayer set up again, but the project doesn't seem to be maintained anymore.

[gardenerik]

I could replicate this bug, increasing stack-size does not fix it, it even seg faulted when stack size was too high.

[rom1504]

I suggest opening an issue on the right repo which is https://github.com/Darthfett/mineflayer-blockfinder

that error is unrelated with scaffold.

[rom1504]

oh and you are doing https://github.com/Darthfett/mineflayer-blockfinder/pull/16/files of course right ?

[gardenerik]

It is related with scaffold, I am not even using bot.findBlock(), just bot.scaffold.to(). I was able to fix this by manually applying #4
