CORS policy

[sdetweil]

@karsten13 ah, I thought we went proxy everywhere

[karsten13]

@sdetweil

had to look in the code again … but may we should set default true for all providers …

[sdetweil]

@karsten13 getting that way

localhost is usually allowed 0.0.0.0 ( I consider to be a bug to send this anywhere) is not

[bicolorbore586]

@sdetweil @karsten13 have added in the useCorsProxy: true

Have since updated MagicMirror, now getting

Could not load data … TypeError: Cannot read properties of undefined (reading ‘0’)

which when clicked on shows weatherbit.js

code_text
```/* global WeatherProvider, WeatherObject */

/* MagicMirror²
 * Module: Weather
 * Provider: Weatherbit
 *
 * By Andrew Pometti
 * MIT Licensed
 *
 * This class is a provider for Weatherbit, based on Nicholas Hubbard's class
 * for Dark Sky & Vince Peri's class for Weather.gov.
 */
WeatherProvider.register("weatherbit", {
	// Set the name of the provider.
	// Not strictly required, but helps for debugging.
	providerName: "Weatherbit",

	// Set the default config properties that is specific to this provider
	defaults: {
		apiBase: "https://api.weatherbit.io/v2.0",
		apiKey: "",
		lat: 0,
		lon: 0
	},

	fetchedLocation: function () {
		return this.fetchedLocationName || "";
	},

	fetchCurrentWeather() {
		this.fetchData(this.getUrl())
			.then((data) => {
				if (!data || !data.data[0] || typeof data.data[0].temp === "undefined") {
					// No usable data?
					return;```

Forgive me, again for being a noob, but I didn’t think this required any information in, however having substituted the lat and lon zero’s for my location, still throws up the same and error and points me to the [0] following !data.data

@bicolorbore586 never edit our code, all config goes in config.js

u need lat and long (how else does it know where u are)

all numbers and true/false have no quotes
anything with a letter or special character does need quotes

u need weatherProvider
apikey
lat
lon
and type (forecast or current)
and

useCorsProxy: true

[bicolorbore586]

@sdetweil
ok, have put it back to how it was… that was final “can I get this to work, before I ask for further help”
this is my config.js

code_text
``` {
			module: "weather",
			position: "top_right",
			config: {
				weatherProvider: "weatherbit",
				type: "current",
				lat: 5,
				lon: -1,
				apiKey: "ab4",
				useCorsProxy: true
					}
		},
		{
			module: "weather",
			position: "top_right",
			header: "Weather Forecast",
			config: {
				weatherProvider: "weatherbit",
				type: "forecast",
				lat: 5,
				lon: -1,
				initialLoadDelay: 1,
				apiKey: "ab4",
				useCorsProxy: true
					}
		},

@bicolorbore586 ok, lousy provider error reporting…

i want you to edit the provider weatherbit.js and

using your config (with the bad apikey) I get the ‘0’ error too

change this (starting on line 38)

					if (!data || !data.data[0] || typeof data.data[0].temp === "undefined") {
						// No usable data?
						return;
					}

					const currentWeather = this.generateWeatherDayFromCurrentWeather(data);
					this.setCurrentWeather(currentWeather);

to this

				if(!data || (data && data.error)){
					Log.error("Could not load data ... ", data?data.error: "no data returned");
				}
				else {
					if (!data || !data.data[0] || typeof data.data[0].temp === "undefined") {
						// No usable data?
						return;
					}

					const currentWeather = this.generateWeatherDayFromCurrentWeather(data);
					this.setCurrentWeather(currentWeather);
				}

then save and
restart mm, open the developers window
ctrl-shift-i
select the console tab
and enter weath
in the filter field

there should be a red line of text , with the weatherbit.js name to the right

[bicolorbore586]

@sdetweil
so I commented out the original text and added in the new:

code_text
``` fetchCurrentWeather() {
		this.fetchData(this.getUrl())
			.then((data) => {
				/*if (!data || !data.data[0] || typeof data.data[0].temp === "undefined") {
					// No usable data?
					return;
				}

				const currentWeather = this.generateWeatherDayFromCurrentWeather(data);
				this.setCurrentWeather(currentWeather);*/
				if(!data || (data && data.error)){
					Log.error("Could not load data ... ", data?data.error: "no data returned");
				}
				else {
					if (!data || !data.data[0] || typeof data.data[0].temp === "undefined") {
						// No usable data?
						return;
					}

					const currentWeather = this.generateWeatherDayFromCurrentWeather(data);
					this.setCurrentWeather(currentWeather);
				}
			})
			.catch(function (request) {
				Log.error("Could not load data ... ", request);
			})
			.finally(() => this.updateAvailable());
