dishwasher module sometimes reads off the end of the buffer and crashes

Here's my code:

require('events').EventEmitter.prototype._maxListeners = 0;

const greenBean = require("green-bean");

function report(name) {
  return function(data) {
    console.log('');
    if (typeof data == 'number') {
      console.log(name + ': ' + data + '; 0x' + data.toString(16) + '; 0b' + data.toString(2));
    } else if (typeof data == 'string') {
      console.log(name + ': "' + data + '"');
    } else if (typeof data == 'object') {
      var s = '';
      for (var f in data) {
        s += ' ' + f + '=' + data[f];
      }
      console.log(name + ': ' + s);
    } else {
      console.log(name + ': (' + typeof data + ') ' + data);
    }
    console.log('');
  }
}

var fields = [
  'cycleStatus', 'operatingMode', 'disabledFeatures', 'reminders', 'rates', 'turbidityCalibration', 'doorCount',
  'userConfiguration', 'error', 'cycleCounts', 'continuousCycle', 'controlLock', 'personality',
  'diverterCalibration', 'cycleState', 'analogData', 'cycleData0', 'cycleData1', 'cycleData2', 'cycleData3',
  'cycleData4', 'dryDrainCounters', 'tubLight'
];

var dishwasher;
greenBean.connect("dishwasher", function(dw) {
    dishwasher = dw;
    var fields = [
      'cycleStatus', 'operatingMode', 'disabledFeatures', 'reminders', 'rates', 'turbidityCalibration', 'doorCount',
      'userConfiguration', 'error', 'cycleCounts', 'continuousCycle', 'controlLock', 'personality',
      'diverterCalibration', 'cycleState', 'analogData', 'cycleData0', 'cycleData1', 'cycleData2', 'cycleData3',
      'cycleData4', 'dryDrainCounters', 'tubLight'
    ];
    for (var index = 0; index < fields.length; index += 1) {
      var field = fields[index];
      if (field in dishwasher)
        dishwasher[field].subscribe(report(field));
      else
        console.log('API doesn\'t have ', field);
    }
});

Here's the output from running it:

$ sudo node listen-dishwasher.js
