javascript - brain.js: equations[0].backpropagate Index(0); ^ TypeError: Cannot read property 'backpropagate Index' of undefined

Question

I am trying to make a neural network in node it keeps giving me the error

const brain = require('brain.js')

const data = require('./trump.json')



const net = new brain.recurrent.LSTM();

const trainingData = data.map(item => ({
    input: item.text,
    output0: item.retweet_count,
    output1: item.favorite_count


}));

const trainRes = net.train(trainingData, {
    iterations: 1000,
    errorThresh: 0.05,
    callback: step => console.log(step)
});



const output1 = net.run('Barrack Obama's sexy ass');

console.log(`Favorites: ${output1}`);
