            .addField({ name: 'ID:', value: `\`\`\`${user.id}\`\`\`` })
            .addField({ name: "Member Since:", value: `\`\`\`<t:${parseInt(member.joinedAt / 1000)}:R>\`\`\``, inline: true })

There's a clear errore here as you are trying to add a field using an object as first and only variable passed, when it needs 3 as done under these two lines. Therefore it can't find a string, and tells you that the field name can't be empty

This is quite a simple debug process that took less than 20 seconds look more into the code for this errors, that should be signaled by a good IDE too.
