Danke, jetzt funktioniert es wieder! :)
Irgendwie funktioniert seit 2 Tagen der Datenabruf nicht mehr. Entweder gar nicht oder die Inzidenzen sind deutlich zu hoch.
Jemand ne Idee was man tun kann?
Schönen Sonntag!
Dürfte daran liegen, dass du eine Widget-Version mit Impfrate verwendest. Hier existiert die bisherige Quelle, von der die Impfzahlen kamen, nicht mehr.
Quick an dirty wäre folgende Lösung:
Den Wert für vaccineStatus wie folgt ändern:
const vaccineStatus = "https://api.corona-zahlen.org/vaccinations";
Und in getVaccineData folgende Änderung:
const attr = data.vaccinated;
->
const attr = data.data.vaccinated;
Plessa kenn ich bin in Elsterwerda geboren.
Vielen Dank für eure Mühe. Ich lerne jeden Tag dazu
Datenabruf vom RKI seit 1. März unterbrochen. Ich habe gelesen, dass vielleicht hier Hilfe vorliegt
marlon360/rki-covid-api#504
Kann das jemand reparieren?
Vielen Dank!
Neue URLs sind im Script eingefügt. Einfach nochmal von oben kopieren und es läuft wieder :-).
