Exception when registering device

[vico]

I got the following Exception when registering my Quaderno 2nd A4. The registration succeeds and I can add documents to my device. But the exception can be resolved by adding update_service to LookUpDPT as suggested.

Exception in thread zeroconf-ServiceBrowser-_dp_fujitsu._tcp-_digitalpaper._tcp-40518:
Traceback (most recent call last):

To skip the discovery process (and this message), call:
    getattr(listener, _ON_CHANGE_DISPATCH[state_change])(zeroconf, service_type, name)

AttributeError: 'LookUpDPT' object has no attribute 'update_service'
    /home/cuong/.local/bin/dptrp1 --addr 192.168.1.41 register

The following snippet will do the job unless there is a plan to add logic for update_service.

        def update_service(self, zeroconf, service_type, name):
              pass
