Weird bug with brain.js

[DrFrankxio]

The error is this:

brain-browser.js:41191 Uncaught TypeError: Cannot read properties of null (reading 'equations')
at LSTM.get (brain-browser.js:41191:22)
at LSTM.run (brain-browser.js:40778:17)
at perceptron.html:37:16

And my code is this:

<script src="https://cdnjs.cloudflare.com/ajax/libs/brain.js/2.0.0-beta.1/brain-browser.js" integrity="sha512-bI0AOBSlsQUR/VlZhVj6PuYqjQFO4YTD6Fpw2UBEGC+QkZWLiDgiFZpDefJFnS+ptTjiwZS30VsaF5vJtkQCGw==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>

[1,0]=><input id="t3"value="1">=>Result:[1,0]=>

[1,1]=><input id="t4"value="1">=>Result:[1,1]=>

<script> const net = new brain.recurrent.LSTM({ inputSize: 2, hiddenLayers: [ { size: 4 }, { size: 2 } ], outputSize: 1 }); render = () => { net.train( [ { input: [0, 0], output: [parseFloat(t1)] }, { input: [0, 1], output: [parseFloat(t2)] }, { input: [1, 0], output: [parseFloat(t3)] }, { input: [1, 1], output: [parseFloat(t4)] }, ], { iterations: 100, // Reducir iteraciones para mayor velocidad log: true, logPeriod: 100, errorThresh: 0.005, } ); isTrained = true; status.textContent = "Training complete!"; updateResults(); } // Permitir al navegador procesar mientras entrena r1.value = net.run({input: [0, 0]}); r2.value = net.run({input: [0, 1]}); r3.value = net.run({input: [1, 0]}); r4.value = net.run({input: [1, 1]}); requestAnimationFrame(render) render() </script>

So, i want all inputs get the same value at each row.
