I had the same problem after migrating from Docker to VM, when i tried to reinstall the integration. This was logged:

File "/config/custom_components/panasonic_cc/config_flow.py", line 49, in _create_entry if entry.data[KEY_DOMAIN] == PANASONIC_DOMAIN: ~~~~~~~~~~^^^^^^^^^^^^ KeyError: 'domain'

Workaround for me was to reaktivate the integration over the disabled entities.
