Having problems using weather-js - node.js

Question

Some monthes ago I followed a tutorial to code a bot that shows weather forecast depending on a stated location. This bot is using weather-js package, but since recently, no matter if I host my bot or launch it through the console, it's working when it wants to, and not working for some locations.
Here is what contains my index.js :
const fs = require('fs');
client.commands = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
for (const file of commandFiles) {
const command = require(`./commands/${file}`);
client.commands.set(command.name, command);
}
\\client.on("ready")....
.....
client.on('messageCreate', async message => {
if (!message.content.startsWith(prefix)) return;
let args = message.content.slice(prefix.length).split(" ");
let command = args.shift().toLowerCase()
if (command === "weather") {
client.commands.get("weather").execute(message, args, Discord, weather)
}
});
and what my weather.js contains:
var weather = require('weather-js');
const Discord = require('discord.js');
module.exports = {
name: 'weather',
description: "Used to get the weather of a place",
execute(message, args, Discord, weather) {
const city = args[0]
weather.find({search: args.join(" "), degreeType: "C"}, function(error, result){
if (error) return message.channel.send(error)
if (!city) return message.channel.send("You must specify a location please!")
if (result === undefined || result.length === 0) return message.channel.send("**Invalid location**")
let current = result[0].current
let location = result[0].location
const embed = new Discord.MessageEmbed()
.setTitle(`Weather forecast for ${current.observationpoint}`)
.setDescription(current.skytext)
.setThumbnail(current.imageUrl)
.setColor("RANDOM")
.setTimestamp()
.addField("Temperature: ", current.temperature + "°C", true)
.addField("Wind Speed: ", current.winddisplay, true)
.addField("Humidity: ", `${current.humidity}%`, true)
.addField("Timezone: ", `UTC${location.timezone}`, true)
message.channel.send({ embeds: [embed]});
})
}
}
I always got that same error when it doesn't work:
throw new DiscordAPIError(data, res.status, request);
^
DiscordAPIError: Cannot send an empty message
at RequestHandler.execute (/home/container/node_modules/discord.js/src/rest/RequestHandler.js:350:13)
at processTicksAndRejections (node:internal/process/task_queues:96:5)
at async RequestHandler.push (/home/container/node_modules/discord.js/src/rest/RequestHandler.js:51:14)
at async TextChannel.send (/home/container/node_modules/discord.js/src/structures/interfaces/TextBasedChannel.js:175:15) {
There's even some locations that were working before, but that suddenly stopped working for any reason!
Has someone had the same problems with weather-js, or is it coming from the code?
Thank you by advance!

One of your line on embed should be a null. That's why its throwing an error. To prevent this. You can use an OR operator.
const embed = new Discord.MessageEmbed()
.setTitle(`Weather forecast for ${current.observationpoint || "NO DATA"}`)
.setDescription(`${current.skytext || "NO DATA"}`) //Using a direct call can cause an error.
.setThumbnail(current.imageUrl) //If this part is the culprit let me know
.setColor("RANDOM")
.setTimestamp()
.addField("Temperature: ", `${current.temperature || "NO DATA"} °C`, true)
.addField("Wind Speed: ", `${current.winddisplay || "NO DATA"}`, true)
.addField("Humidity: ", `${current.humidity || "NO DATA"}%`, true)
.addField("Timezone: ", `UTC${location.timezone || "NO DATA"}`, true)
message.channel.send({ embeds: [embed]});
The || symbols is a OR operator.
