AirNow integration incorrectly assumes all responses have PM2.5 data

The problem

I've been getting this error in the logs:

KeyError: 'DateObserved'

Digging into the Python code, this is because the code assumes that one of the observations will have PM2.5 data, but my response only has O3 data, so the date information, while present in the original response, doesn't get copied over.

The response JSON (redacted):

[
    {
        "DateObserved": "2024-04-23",
        "HourObserved": 20,
        "LocalTimeZone": "EST",
        "ReportingArea": "*redacted*",
        "StateCode": "*redacted*",
        "Latitude": 1.0,
        "Longitude": -1.0,
        "ParameterName": "O3",
        "AQI": 45,
        "Category": {
            "Number": 1,
            "Name": "Good"
        }
    }
]

Sorry, I'm still seeing this in the latest version.

I am seeing the same issue and error logged in my instance of HA, too.

[monsieurlatte]

I am as well, seems the codebase owner hasn't been able to fix this yet :(
