openweather ONE call API

[pioneersteffen]

I trying to integrate the alerts as well. Unfortuantely I getting the following error:

Code:

Openweathermap 22.10.2021 19:39:38
User script:52: attempt to index global 'alerts' (a nil value)
stack traceback:
User script:52: in main chunk

Do you have an idea what might be wrong?

Here is the complete code:

Code:

require('json')
http = require('socket.http')

appid = 'xxx'
lat = 'xxx'
lon ='xxx'
lang = 'de'
units = 'metric'

url = 'http://api.openweathermap.org/data/2.5/onecall?lat=%s&lon=%s&units=%s&lang=%s&appid=%s'
url = string.format(url, lat, lon, units, lang, appid)

res, code, headers, status = http.request(url)
log (code, status, headers)
data = json.pdecode(res)

--Fault messages:
if not data then
  alert('Error converting data')
  return
end

if not res then
  alert('Error collecting data')
  return
end

current = data.current
daily = data.daily[1]
alerts = data.alerts


-- current temperature
grp.write('41/1/1', current.temp)
--current Humidity
grp.write('41/1/3', current.humidity)
--current wind speed
grp.write('41/1/6', current.wind_speed)
--daily forecast Temperature min
grp.write('41/1/4', daily.temp.min)
--daily forecast Temperature max
grp.write('41/1/5', daily.temp.max)
-- daily Weather condition
grp.write('41/1/2', daily.weather[1].description)
--daily forecast wind gust
grp.write('41/1/7', daily.wind_gust)
--daily forecast max UV Index
grp.write('41/1/8', daily.uvi)
--daily forecast max UV Index
grp.write('41/1/9', daily.rain)
--alerts
grp.write('41/1/10', alerts.event)

wetterprognose = math.ceil(daily.temp.min).."/"..math.ceil(daily.temp.max).."/"..daily.rain.."/"..math.ceil(daily.wind_gust).."/"..math.ceil(daily.uvi)

--sending daily weather forecast to MDT Taster
grp.write('41/2/1', wetterprognose)

Many thanks for your help!
