Z2M External Converter Setup Error

Configuration Zigbee
1

I have been trying to setup these Enkin / Elesi Zigbee Smart Dimmers using the Z2M Support New Devices Guide.

Everything works well until the end of part 2, where when using the example ‘Bulb (Light)’ .js script:

const fz = require('zigbee-herdsman-converters/converters/fromZigbee');
const tz = require('zigbee-herdsman-converters/converters/toZigbee');
const exposes = require('zigbee-herdsman-converters/lib/exposes');
const reporting = require('zigbee-herdsman-converters/lib/reporting');
const legacy = require('zigbee-herdsman-converters/lib/legacy');
const extend = require('zigbee-herdsman-converters/lib/extend');
const ota = require('zigbee-herdsman-converters/lib/ota');
const tuya = require('zigbee-herdsman-converters/lib/tuya');
const utils = require('zigbee-herdsman-converters/lib/utils');
const globalStore = require('zigbee-herdsman-converters/lib/store');
const e = exposes.presets;
const ea = exposes.access;

const definition = {
    zigbeeModel: ['ZDM150'],
    model: 'ZDM150',
    vendor: 'Enkin',
    description: 'Elesi Dimmer',
    extend: extend.light_onoff_brightness
};

module.exports = definition;

the addon won’t start and I get this error:

[18:06:51] INFO: Preparing to start...

I have got it working as just a switch, without the dimming using this example:

const fz = require('zigbee-herdsman-converters/converters/fromZigbee');
const tz = require('zigbee-herdsman-converters/converters/toZigbee');
const exposes = require('zigbee-herdsman-converters/lib/exposes');
const reporting = require('zigbee-herdsman-converters/lib/reporting');
const extend = require('zigbee-herdsman-converters/lib/extend');
const e = exposes.presets;
const ea = exposes.access;

const definition = {
    zigbeeModel: ['ZDM150'],
    model: 'ZDM150',
    vendor: 'Enkin',
    description: 'Elesi Dimmer',
    fromZigbee: [fz.on_off],
    toZigbee: [tz.on_off],
    exposes: [e.switch()],
    configure: async (device, coordinatorEndpoint, logger) => {
        const endpoint = device.getEndpoint(1);
        await reporting.bind(endpoint, coordinatorEndpoint, ['genOnOff']);
        await reporting.onOff(endpoint);
    },
};

module.exports = definition;

The error seems to be coming from the zigbee-herdsman-converters library which is copied straight from the example code on the Z2M tutorial. Anyone encountered this and have a fix?

Thanks in advance for any help.
