We Connect service not avaible (beacuse of issue / outage on Volkswagen)

Describe the bug

Yesterday there was an outage at Volkswagen (see also this report: https://downdetector.co.uk/status/we-connect-go/) This results in the not working of this integration anymore, which makes sense of course. I notice a bunch of errors putting every 30 seconds into the log file.

Is it possible to have a global detection if data can be retrieved if not retry or pause of a few minutes?

Debug log

This is the error related to the outage (line number can be different because I have some modifications):

  File "/config/custom_components/volkswagen_we_connect_id/number.py", line 70, in native_value
    if self.data.domains["charging"]["chargingSettings"].targetSOC_pct.value:
       ~~~~~~~~~~~~~~~~~^^^^^^^^^^^^
KeyError: 'charging'

This is the whole error each 30 sec:
