Is my Espruino sleeping?

So i've read the docs and I do indeed have console logs in my code, so my plan is to remove those, but I've somehow hit another issue. When I try to send code to my board i'm getting the following error.

New interpreter error: FIFO_FULL
Connection error: No 'ready' after AT+RST

This is odd as it has been working from the web IDE just fine recently. Here's the source. I have a raspberry pi4 running nodered which reads sensors around the house, some of these send data via MQTT which i'm picking up with the Espruino Wifi.

const neo = require('neopixel');
const wifi = require('Wifi');
const WIFI_NAME = 'BTHub6-3TFX';
const WIFI_OPTIONS = { password : 'xxxxxxxx' };

let delay = 0;
let rgb = new Uint8ClampedArray(36);


function onInit() {
  setSleepIndicator(LED1);
  const server = '192.168.1.64';
  const options = {
    client_id : 'random',
    keep_alive: 60,         // keep alive time in seconds
    port: 1883,             // port number
    clean_session: true,
    username: 'username',   // default is undefined
    password: 'password',   // default is undefined
    protocol_name: 'MQTT',  // or MQIsdp, etc..
    protocol_level: 4,      // protocol level
  };
  const mqtt = require('MQTT').create(server, options /*optional*/);

  mqtt.on('connected', () => {
    console.log('connected to broker');

    mqtt.subscribe('doorOpen');
    mqtt.subscribe('doorClosed');
    mqtt.subscribe('heartbeat');
  });

  mqtt.on('publish', (pub) => {
    console.log('topic: '+pub.topic);
    console.log('message: '+pub.message);

    switch(pub.topic) {
      case 'doorOpen':
        console.log('doorOpen');
        doorOpen();
        break;

      case 'doorClosed':
        console.log('doorClosed');
        doorClosed();
        break;

      case 'heartbeat':
        if(parseInt(pub.message) > 1) {
          heartbeat();
        }else{
          motion();
        }
        break;

      default:
        neo.write(B15, lights({r: 0, g: 0, b: 0}));
        break;
    }

  });

  wifi.connect(WIFI_NAME, WIFI_OPTIONS, (err) => {
    if (err) {
      console.log('Connection error: '+err);
      return;
    }
    console.log('Connected!');
    mqtt.connect();
  });

  function lights(colors) {
    for (let i = 0; i < rgb.length;) {
      rgb[i++] = colors.g;
      rgb[i++] = colors.r;
      rgb[i++] = colors.b;
    }
    return rgb;
  }

  function doorOpen() {
    neo.write(B15, lights({r: 0, g: 0, b: 0}));
    update({r: 255, g: 0, b: 0});
  }

  function doorClosed() {
    neo.write(B15, lights({r: 0, g: 0, b: 0}));
    update({r: 0, g: 255, b: 0});
  }

  function heartbeat() {
    neo.write(B15, lights({r: 0, g: 0, b: 0}));
    update({r: 0, g: 0, b: 255});
  }

  function motion() {
    neo.write(B15, lights({r: 0, g: 0, b: 0}));
    update({r: 0, g: 255, b: 0});
  }

  function update(color) {
    neo.write(B15, lights(color));
    delay = setTimeout(() => {
      neo.write(B15, lights({r: 0, g: 0, b: 0}));
    }, 1000);
  }
}

onInit();
