Check if the image exists to .setImage In Embed - discord

Question

First of all sorry for the bad English
I'm trying to do a "tweet" system. I check if the link is true and has an image but if you put something like https://askhdkjahs.png the program thinks is an image and put in the embed giving an error
I need handle the error and put a default image or reply saying 'the image give a error'
thats my code
if (comando === `${prefix}atwt`) {
msg.delete({ timeout: 100 });
if (!argumento[0]) {
msg.reply('pon algo').then(msg => {
msg.delete({ timeout: 10000 });
}).catch(console.error);
}
else if(argumento !== null && argumento !== '') {
const TweetAnon = new Discord.MessageEmbed()
.setAuthor('Anonimo!', 'https://i.imgur.com/wSTFkRM.png')
.setColor('BLUE')
.setTimestamp();
const url = argumento[0].toString();
if (url.match(/^https.*\.(png|jpeg|jpg|gif|bmp)$/i)) {
TweetAnon.setImage(argumento[0]);
TweetAnon.setDescription(`**${argumento.slice(1).join(' ')}**`);
}
else{
TweetAnon.setDescription(`**${argumento.join(' ')}**`);
}
const msgEmbed = await msg.channel.send(TweetAnon).catch(TweetAnon.setImage('https://i.imgur.com/wSTFkRM.png'));
await msgEmbed.react('👍');
await msgEmbed.react('👎');
await msgEmbed.react('🔄');
}
}
I see something like that and I tried but doesn't work
if (comando === `${prefix}atwt`) {
const url = argumento[0].toString();
const TweetAnon = new Discord.MessageEmbed()
.setAuthor('Anonimo!', 'https://cdn.discordapp.com/attachments/769965806850670634/854834517709422602/anon.png')
.setColor('BLUE')
.setTimestamp();
msg.delete({ timeout: 100 });
try {
if (!url.match(/^https.*\.(png|jpeg|jpg|gif|bmp)$/i)) {
throw new Error('Invalid URL');
}
TweetAnon.setImage(argumento[0]);
TweetAnon.setDescription(`**${argumento.slice(1).join(' ')}**`);
}
catch (error) {
TweetAnon.setImage('https://i.imgur.com/wSTFkRM.png');
}
// else
// TweetAnon.setDescription(`**${argumento.join(' ')}**`);
// }
const msgEmbed = await msg.channel.send(TweetAnon).catch(err => console.log(err));
await msgEmbed.react('👍');
await msgEmbed.react('👎');
await msgEmbed.react('🔄');
}

You could check if the image exists like this:
function imageExists(image_url){
var http = new XMLHttpRequest();
http.open('HEAD', image_url, false);
http.send();
return http.status != 404;
}
Usage:
if(imageExists(argumento[0])){
TweetAnon.setImage(argumento[0]);
}
