@reiryoku/ctrader-layer Does this library still work

I'm trying to setup a web socket in .js using an existing library however all my responses are as follows.

📊 Tick Update: Payload undefined or missing
Full response CTraderLayerEvent {}
📊 Tick Update: Payload undefined or missing
Full response CTraderLayerEvent {}
📊 Tick Update: Payload undefined or missing
Full response CTraderLayerEvent {}

This happens for both execution and ticks. Does anyone know if @reiryoku/ctrader-layer library or does this not work anymore?

Thanks
