Cannot get a new installation going

[Lectere]

Im on the latest HAOS, install the HACS component, try to add the integration, fill in the details, using GAD in the Netherlands. Cannot submit get a "unknown error".

I leave everything as default as possible. Cannot trouble shoot. I don't see any requirements. Is it maybe because my postcode / house number is not included? Does it rely on other integrations (calander?)?

The source you're using (hvcgroep_nl) set The TITLE parameter weirdly, so the config_flow (GUI Configuration fails), I fixed this in #2879

This will be part of the next release or is available now as master (git) version

install master/git: Developer tools -> actions -> select update: Install update -> click Coose entity and select WCS -> select version and type master in the input field -> run the action -> restart HA

Older versions of HACS:

install master with HACS version < 2.0: (3-dot menu -> redownload -> change version to master -> fully restart HA (this will increase update cycle by a lot)
