I've tried to find the solution to my issue on this forum and general web searches. I see a lot of similar issues but no clear advice how to answer. I have some fairly simple code to get a .daily historical weather object as below: var gameLocation: CLLocation = CLLocation() switch game.country { case .us: gameLocation = CLLocation(latitude: homeTeam.sFactors.gpsCoord.lat, longitude: homeTeam.sFactors.gpsCoord.long) case .germany: gameLocation = CLLocation(latitude: GameCountry.germany.gpsCoord.lat, longitude: GameCountry.germany.gpsCoord.long) case .uk: gameLocation = CLLocation(latitude: GameCountry.uk.gpsCoord.lat, longitude: GameCountry.uk.gpsCoord.long) case .mexico: gameLocation = CLLocation(latitude: GameCountry.mexico.gpsCoord.lat, longitude: GameCountry.mexico.gpsCoord.long) } var gameStartDate: Date = Date() do { gameStartDate = try DateRelatedHelpers().convertISO8601StringToDate(from: game.date) print("Date string: \(game.date), Date: \(gameStartDate)") } catch { throw DateHelperError.invalidDateString } let gameEndDate = Calendar.current.date(byAdding: .day, value: 1, to: gameStartDate)! let gameWeather = try! await weatherService.weather(for: gameLocation, including: .daily(startDate: gameStartDate, endDate: gameEndDate)) I call the function from a loop which is going through several different locations to fetch. I get some valid responses then I receive the following error: Received invalid http response code 404 for request: C2A50990-2E03-497B-BC48-EF7560524E00 Encountered an error when fetching weather data subset; location=<+39.27745100,-76.62297400> +/- 0.00m (speed -1.00 mps / course -1.00) @ 1/24/24, 8:32:28 PM Central Standard Time, error=responseFailed: 404 WeatherDaemon.WDSClient<WeatherDaemon.WeatherResource>.Errors.responseFailed(<NSHTTPURLResponse: 0x6000003d5dc0> { URL: https://weather-data.apple.com/v3/weather/en-US/39.277/-76.623?timezone=America/New_York&dataSets=forecastDaily&dailyStart=2023-09-10T17:00:00Z&dailyEnd=2023-09-11T17:00:00Z&country=US&deviceLanguages=en-US&clientMetadata=CgJVUxoFZW4tVVNKAFABWBRgA4ABA5gBALoBAhAB4gEICgseHR8hICLyAQJVUw } { Status Code: 404, Headers { "Access-Control-Allow-Origin" = ( "*" ); "Cache-Control" = ( "max-age=0, no-cache, no-store" ); Connection = ( "keep-alive" ); "Content-Length" = ( 0 ); "Content-Security-Policy" = ( "default-src 'self';" ); Date = ( "Thu, 25 Jan 2024 02:32:29 GMT" ); Expires = ( "Thu, 25 Jan 2024 02:32:29 GMT" ); Pragma = ( "no-cache" ); Server = ( Apple ); "Strict-Transport-Security" = ( "max-age=31536000; includeSubdomains" ); "X-Apple-Origin" = ( "f6fe362e-be7c-35f4-b131-3b1f903b4bca" ); "X-Cache" = ( "TCP_MISS from a184-28-40-133.deploy.akamaitechnologies.com (AkamaiGHost/11.4.0-53477943) (-)" ); "X-Content-Type-Options" = ( nosniff ); "X-Frame-Options" = ( SAMEORIGIN ); "X-REQUEST-ID" = ( "C2A50990-2E03-497B-BC48-EF7560524E00" ); "X-XSS-Protection" = ( "1; mode=block" ); } }, Optional("")) I also get this warning on any call that receives data: Aborting silent interpolation: additional missing products that need to be fetched from the server anyway; location=CLLocationCoordinate2D(latitude: 39.277451, longitude: -76.622974), missing products=[WeatherDaemon.WeatherProduct.forecastDaily] My dates are in UTC time. I assume the calls return data in the local time of the location. Could this be an issue with Dates (i.e. local vs location date)? Any assistance would be appreciated.
