(Homebridge) TypeError: Init Error

[Will-Mann-16]

Hello everyone, I was trying to setup this package on my RP4 with HomeBridge to see if I could control my LED strip from my iPhone. No luck so far, as I'm getting this error:
[9/21/2020, 00:12:13] [Lightstrip] Initializing Lightstrip accessory... Can't open /dev/mem: Operation not permitted error initializing -5 mmap() failed [9/21/2020, 00:12:13] TypeError: Init Error at EventEmitter.ws281x.init (/home/pi/Documents/strip-controller/homebridge-lightstrip/node_modules/rpi-ws281x-native/lib/ws281x-native.js:138:14) at new LightstripAccessory (/home/pi/Documents/strip-controller/homebridge-lightstrip/index.js:31:25) at /usr/local/lib/node_modules/homebridge/src/server.ts:355:50 at Array.forEach (<anonymous>) at Server._loadAccessories (/usr/local/lib/node_modules/homebridge/src/server.ts:328:29) at Server.start (/usr/local/lib/node_modules/homebridge/src/server.ts:154:12) at cli (/usr/local/lib/node_modules/homebridge/src/cli.ts:80:10) at Object.<anonymous> (/usr/local/lib/node_modules/homebridge/bin/homebridge:17:22) at Module._compile (internal/modules/cjs/loader.js:1137:30) at Object.Module._extensions..js (internal/modules/cjs/loader.js:1157:10) [9/21/2020, 00:12:13] Got SIGTERM, shutting down Homebridge...

I've setup HomeBridge with a superuser, and I've tested the package/code with the rainbow file, and it works, so I don't exactly know what's going on here. Any ideas? I would be eternally grateful.

If anyone wants it, my code for the Accessory Controller for HomeBridge - pendant on a solution:
`const colorsys = require('colorsys');

const LED_COUNT = 300;

module.exports = api => {
api.registerAccessory('Lightstrip', LightstripAccessory);
}

function rgb2Int(r, g, b) {
return ((r & 0xff) << 16) + ((g & 0xff) << 8) + (b & 0xff);
}

class LightstripAccessory{
constructor(log, config, api){
this.log = log;
this.config = config;
this.api = api;

    this.Service = this.api.hap.Service;
    this.Characteristic = this.api.hap.Characteristic;

    this.log.debug('Lightstrip Accessory Plugin Loading...')

    this.informationService = new this.Service.AccessoryInformation();
    this.informationService.setCharacteristic(this.Characteristic.Manufacturer, "CHINLEY");
    this.informationService.setCharacteristic(this.Characteristic.Model, "LED Strip Light SMD5050");

    this.lightService = new this.Service.Lightbulb(this.name);

    this.controller = require('rpi-ws281x-native');
    this.controller.init(LED_COUNT);

    this.activeData = [];
    this.on = false;
    this.hue = 0;
    this.saturation = 0;
    this.brightness = 0;

    this.lightService.getCharacteristic(this.Characteristic.On).on('get', this.handleGetOn.bind(this)).on('set', this.handleSetOn.bind(this));
    this.lightService.getCharacteristic(this.Characteristic.Hue).on('get', this.handleGetHue.bind(this)).on('set', this.handleSetHue.bind(this));
    this.lightService.getCharacteristic(this.Characteristic.Saturation).on('get', this.handleGetSaturation.bind(this)).on('set', this.handleSetSaturation.bind(this));
    this.lightService.getCharacteristic(this.Characteristic.Brightness).on('get', this.handleGetBrightness.bind(this)).on('set', this.handleSetBrightness.bind(this));

    // process.on('SIGINT', function () {
    //     this.controller.reset();
    //     process.nextTick(function () { process.exit(0); });
    //   });

    this.log.debug('Lightstrip Accessory Plugin Loaded')

}

getServices() {
    return [
      this.informationService,
      this.lightService,
    ];
  }

render(){
    if(this.on){
        let { r, g, b } = colorsys.hsvToRgb(this.hue, this.saturation, this.brightness);
        for(let i = 0; i < LED_COUNT; i++){
            this.activeData[i] = rgb2Int(r, g, b);
        }
    } else {
        this.activeData = [];
    }
    this.controller.render(activeData);
}

handleGetOn(callback){
    callback(null, this.on);
}
handleSetOn(value, callback){
    this.on = value;
    this.render();
    callback(null);
}

handleGetHue(callback){
