Error whilst connecting to Wallbox Quasar

[desolina-nz]

Hi, I'm trying to connect through to a wallbox Quasar. On the wallbox app, it always shows just "connecting...." In HA it does seem to temporarily connect and some of the entities populate with real data so I know its starting to work. But every time it then losses the connection and goes unavailable after about 30s.

On HA logs I'm getting this below. Can anyone help?

This error originated from a custom integration.

Logger: custom_components.ocpp

Integration: Open Charge Point Protocol (OCPP) (documentation, issues)

The above exception was the direct cause of the following exception:
