Error occurred loading flow for integration uk_bin_collection: No module named 'uk_bin_collection'

[farnz]

I've just added the integration to my Home Assistant setup (using the official container), and restarted HA. When I try to add this integration, I get an error in the UI:

Config flow could not be loaded: {"message":"Invalid handler specified"}

When I look at HA logs, I see:

Dec 01 18:59:59 parrot.farnz.org.uk homeassistant[258840]: 2024-12-01 18:59:59.615 ERROR (MainThread) [homeassistant.config_entries] Error occurred loading flow for integration uk_bin_collection: No module named 'uk_bin_collection'

My HA install claims to be:

• Core 2024.11.3
• Frontend 20241106.2

Any idea what I've done wrong?
