JS heap out of memory for the example task

[milesway]

Program exit with FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory when executing the sample task:

const mineflayer = require('mineflayer')

const bot = mineflayer.createBot({
  host: 'localhost', 
  username: 'bot1', 
  auth: 'offline',
  port: 2037,  
})

// Load collect block
bot.loadPlugin(require('mineflayer-collectblock').plugin)

async function collectStone() {
  // Find a nearby stone block
  const stone = bot.findBlock({
    matching: mcData.blocksByName.stone.id,
    maxDistance: 64
  })

  if (stone) {
    // If we found one, collect it.
    try {
      await bot.collectBlock.collect(stone)
      collectStone() // Collect another stone block
    } catch (err) {
      console.log(err) // Handle errors, if any
    }
  }
}
// On spawn, start collecting all nearby stone
bot.once('spawn', () => {
  mcData = require('minecraft-data')(bot.version)
  collectStone()
})

The stone is right next to the agent, and agent is not mining.

You are not waiting for promises correctly.

You are not waiting for promises correctly.

@extremeheat Could you elaborate more about how to do it? As it is the example code on README I am using.
