Some Image Tags are Broken

All,

I an frequently having problems with some of the icons returned from:

https://api.weather.gov/gridpoints/ALY/92,50/forecast/hourly

For example, in the following response:

"periods": [
        {
            "number": 1,
            "name": "",
            "startTime": "2024-01-01T23:00:00-05:00",
            "endTime": "2024-01-02T00:00:00-05:00",
            "isDaytime": false,
            "temperature": 23,
            "temperatureUnit": "F",
            "temperatureTrend": null,
            "probabilityOfPrecipitation": {
                "unitCode": "wmoUnit:percent",
                "value": 0
            },
            "dewpoint": {
                "unitCode": "wmoUnit:degC",
                "value": -7.7777777777777777
            },
            "relativeHumidity": {
                "unitCode": "wmoUnit:percent",
                "value": 81
            },
            "windSpeed": "6 mph",
            "windDirection": "NW",
            "icon": "https://api.weather.gov/icons/land/night/sct,0?size=small",
            "shortForecast": "Partly Cloudy",
            "detailedForecast": ""
        },

it returns the following icon:

https://api.weather.gov/icons/land/night/sct,0?size=small

However, attempting to retrieve the icon returns an error:

{
"correlationId": "13f7665e",
"title": "Bad Request",
"type": "https://api.weather.gov/problems/BadRequest",
"status": 400,
"detail": "Bad Request",
"instance": "https://api.weather.gov/requests/13f7665e"
}

It seems like if I remove the ',0' it sometimes (usually?) works, as in:

https://api.weather.gov/icons/land/night/sct?size=small

but before I put in code to automatically do that, I would like to understand what the problem is, and if it is always consistent (e.g., should I always change /sct,0/ to /sct/) ?

Please advise.

Thanks,

Dave Filip

It’s an old bug. See this from April 2023:
#633

I responded on that discussion that I replace “,0?” with “?”. Note: I believe this problem only shows up for the hourly forecast. For the 12-hour, zero percent POP is not appended to the URL.

I don’t recall anyone saying this may be fixed one day.

Great, thanks for confirming the issue. Hopefully it will be fixed at some point, but at least until then I understand what is causing this. To be honest, until looking closer at this, I didn't realize that the ",#' meant that the icons were being dynamically altered based on the percent precipitation, but now that I look closer at it, I get that.

I'm just happy that on Jan 1, 2024 the /forecast/hourly endpoint started working again! Since it broke towards the end of 2023, I was afraid I was going to have to find a new Weather API.
