Describe the issue

Panasonic Comfort Cloud integration fails for my Aquarea device.

Home Assistant log shows:

The hub can be created and the login form is accepted, but no devices/entities are created and the integration crashes.

Home Assistant integration page also gives config flow errors / 500 Internal Server Error.
