Default Weather module still not displaying

[Jarhead96097]

@sdetweil sorry, already using your installation script (but no “npm audit fix” this time around).

@sdetweil On my RPi4 it’s 16.16.0, and I’m getting the same problems as Jarhead. After an upgrade there’s now just no reaction to starting mm.

[sdetweil]

@Blackeye can u show the output of the npm start or, if using pm2 , then

pm2 logs --lines=50

how did u do the upgrade?

[sdetweil]

@Blackeye also, can u show me the contents of line 159 from

~/MagicMirror/modules/default/weather/weather.js

@OldSunGuy I use the MMM-ModuleScheduler 3rd party module to control when my MM turns off everything except the clock and dims the display at night. “daytime_scheduler” is the class I used to turn off those modules at night.

@sdetweil here is what my weather.js (newly rebuilt, but not yet configured) has on lines 148 to 166:

	// What to do when the weather provider has new information available?
	updateAvailable: function () {
		Log.log("New weather information available.");
		this.updateDom(0);
		this.scheduleUpdate();

		if (this.weatherProvider.currentWeather()) {
			this.sendNotification("CURRENTWEATHER_TYPE", { type: this.weatherProvider.currentWeather().weatherType.replace("-", "_") });
		}

		const notificationPayload = {
			currentWeather: this.weatherProvider?.currentWeatherObject?.simpleClone() ?? null,
			forecastArray: this.weatherProvider?.weatherForecastArray?.map((ar) => ar.simpleClone()) ?? [],
			hourlyArray: this.weatherProvider?.weatherHourlyArray?.map((ar) => ar.simpleClone()) ?? [],
			locationName: this.weatherProvider?.fetchedLocationName,
			providerName: this.weatherProvider.providerName
		};
		this.sendNotification("WEATHER_UPDATED", notificationPayload);
	},

@sdetweil Sam, thanks for all of your help. I’ve finished rebuilding without running ‘npm audit fix’ and everything is working as it should! I used your installation script and everything worked fine. I also took the opportunity to move things around and try a couple of new 3rd party modules… everything is back to normal!

Thanks again,

@Jarhead96097 said in Default Weather module still not displaying:

  const notificationPayload = {
  	currentWeather: this.weatherProvider?.currentWeatherObject?.simpleClone() ?? null,

thats line 158 and159.

the only thing i can think of is the ?. (optional chaining) operator…
but its been long supported… and it works on my 16.9.1 node version

see item 2 in the list here

@Jarhead96097 great news!!!

@sdetweil Moin, line 159 of weather-js looks like this:

currentWeather: this.weatherProvider?.currentWeatherObject?.simpleClone() ?? null,

The pm2 error log shows:

/home/<myusername>/.pm2/logs/MagicMirror-error.log last 50 lines:

Looks like I should re-install. Which is the best method, in your opinion?
Many thanks for your help - I want to get this thing on the wall soon!
