Core: PostNL component broken

[peternijssen]

Integration:
https://www.home-assistant.io/integrations/postnl/

Description of problem:
The PostNL component seems to be broken again, shortly after a fix has been applied. A bug report is ongoing in the connected library: https://github.com/iMicknl/python-postnl-api/issues/17

So far research is still on going and no active solution yet. It seems to break for all HA versions and sooner or later people might experience this issue.

This issue is merely to proactively have this issue in the issue list, being able to add an alert and connect it with mentioned library.

Is this the same error?

I also see the same error as above:

It is an (Python) API issue, that they are trying to resolve (see here for example: https://github.com/iMicknl/python-postnl-api/pull/22)

I got in touch today with PostNL and it seems they are willing to help out. Will post updates in the Lovelace thread if there is any development on this.
