Error Undefined Property MMM-OpenWeatherForecast

[quetown]

Error: MMM-OpenWeatherForecast.js:290 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading ‘weather’)

This is the line of code:
processWeatherData: function() {
var timeZoneOffset = this.weatherData.timezone_offset;
var summary = this.weatherData.current.weather[0].description.substring(0,1).toUpperCase() + this.weatherData.current.weather[0].description.substring(1) + “.”;

@quetown this means the data doesn’t match the expected format.

either the data format has changed
or
the wrong data type was returned (the module expected a multiday list, but got a single day result)

without debugging the actual cause, fixing is not possible.

I suspect the apikey is for the wrong service
