BP03: TypeError: Cannot read properties of undefined (reading '1')

[6illess]

Dyson Purifier Big+Quiet Formaldehyde makes Homebridge crash when turning it on/off via this plugin.
I haven't enabled any additional settings within the plugin config.
Strange thing is that the command on/off does get through and thus the Dyson reacts on it but it makes the application crash immediately:
