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) + “.”;

@sdetweil Thanks!

Re: MMM-OpenWeatherForecast - Replacement for MMM-DarkSkyForecast

On the config name value pairs for this module and the same for the other modules. Is it better to put the configs in the JS file in the module or in the MM Config.js file?

2nd question, is which one overrides the other. Does the Config.js override any value found in the module.js file or the other way around?
Thanks for the help.
