Empty literal breaks AppDaemon apps integration

[robertodelgado16]

After generating new data for my home assistant instance I see fields are set as empty literals. When I run AppDaemon I see the following error:

2026-08-04 19:43:38.300532 ERROR Error: =====  Error importing 'security.frigate'  ================================

The fix is to just add a value to the Literal such as Literal['']

Thanks for opening this issue!

Ah so it's an enum with no possible value basically? Could you send me the relevant part of entities.json and possibly services.json that gets generated when you run hapt.py with -d? (Probably filter and anonymize it because otherwise it may contain your personal data.) (Basically I'm looking for the actual state and attributes of that entity so I can understand what it gives that we generate poorly for.)

My guess is we'd rather want to use str or any here rather than enforcing that caller always passes an empty string, as your proposed fix would imply.

I found this as the related entity in entities.json. Found nothing in services.json

    {
        "entity_id": "select.SOME_ENTITY",
        "state": "unknown",
        "attributes": {
            "options": [],
            "friendly_name": "SOME_FRIENDLY_NAME"
        },
        "last_changed": "2026-08-05T01:34:28.501535+00:00",
        "last_reported": "2026-08-05T01:34:28.501535+00:00",
        "last_updated": "2026-08-05T01:34:28.501535+00:00",
        "context": {
            "id": "SOME_ID",
            "parent_id": null,
            "user_id": null
        }
    },
