Periodic errors in plasmashell log: QML XmlListModelRole: Query error: "Attribute value not found"

[shmerl]

I see such kind of errors in systemd user log for plasmashell (something in OpenWeatherMap.qml:612:9), each time weather widget checks weather conditions (using a station from OpenWeather Map):

... plasmashell[2380]: file:///home/user/.local/share/plasma/plasmoids/org.kde.weatherWidget-3/contents/ui/providers/OpenWeatherMap.qml:612:9: QML XmlListModelRole: Query error: "Attribute value not found

The way I check it:

sudo journalctl _SYSTEMD_USER_UNIT=plasma-plasmashell.service
