Error on events.js:174 during homebridge loading

[monsterciattolo]

I'm using homebridge in a docker "oznu/docker-homebridge" with network in bridge mode.
All other plugins are working fine but this one no.

nodejs 10.15.3

Homebridge continues to restart with this error below

TypeError [ERR_INVALID_ARG_TYPE]: The first argument must be one of type string, Buffer, ArrayBuffer, Array, or Array-like Object. Received type undefined

Any idea?
