Im working in a avatar command that works with ID and mentions, but when a type something like "!avatar hello" didn't catch nothing and dies :(

• What's your exact discord.js npm list discord.js and node node -v version?
• Post the full error stack trace, not just the top part!
• Show your code!
• Explain what exactly your issue is.

Then you seem to have a catch somewhere that silently ignores the error… or you didn’t check the console for errors. Because mention will be undefined in your case and thus you can’t access any properties on it

[north lagoon]

this is the console error, I searched about it but nothing that actually helps

[tacit sierra]

You pass your args[0] to the get without making sure it‘s a id. Try using guild.members.resolve(…) instead and check if it exists before trying to access properties

it works fine with mentions but id mentions didnt work now

What does your code look like now?

////////////////AVATAR////////////////

client.on('messageCreate', async message => {
    const prefix = "tr.";
    const args = message.content.slice(prefix.length).split(/ +/);
    const command = args.shift().toLowerCase();
    if(message.content.toLowerCase().startsWith(prefix))
      {
          if(command === "av") {

            let mention = message.mentions.users.first().id || (await message.guild.members.fetch(args[0])).id
            let m = mention.username
            if(mention.id == undefined) return;
                const embed = new MessageEmbed()
                  .setColor(`0x2F3136`)
                  .setDescription('aqui esta el avatar 👍')
                  .setImage(await mention.displayAvatarURL({size: 4096, dynamic: true}))
                  .setFooter({text: `Avatar de ${m}`})
                  message.reply({ embeds: [embed] }).catch(() => null)
        }
    }
});

Why did you make mention the id now? Strings don’t have .id or .username property

And it will obviously fail again if the fetch returns undefined

[north lagoon]

I was trying any thing just in case

obviously didnt work

[carmine sandal]

just add a .catch(() => null) after the fetch and then check if mention exists

something like:

let mention = message.mentions.users.first() || await message.guild.members.fetch(args[0]).catch(() => null);

if(!mention) return message.channel.send('No user found') 

BTW you don't need the await in the displayAvatarURL function
