Cannot read properties of undefined (reading 'rows')

Im trying to make a chat bot but I keep getting an error when I try and start it so it will learn

Code:

const fs = require('fs')
const readline = require('readline')
const brain = require('brain.js')
const net = new brain.recurrent.LSTM()

const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout
})

const array = []

fs.readFile('learned.json', (err, data) => {
  if(err) return console.log(err)

  if(data.toString() === '') {
    console.log('Network already trained.')
    train()
  } else {
    net.fromJSON(JSON.parse(data.toString()))
    boot()
  }
})

const train = () => {
  console.log('Training...')
  const d = new Date()
  fs.readFile('essay.txt', (err, data) => {
    array = data.toString().split('.')
    net.train(array, {
      iterations: 20000,
      log: true,
      errorThresh: 0.01
    })
    fs.writeFile('learned.JSON', JSON.stringify(net.toJSON()))
    console.log(`Training finished in ${(new Date() - d) / 1000} s`)
  })
}

const boot = () => {
  rl.question('Enter: ', (q) => {
    console.log(net.run(q))
    boot()
  })
}

Could you provide a sample of the data from the learned.json file?
