Why is there an error when outputting information?

Question

JavaScript

I decided to study the Canvas library, with the help of a guide, I wrote a code that should display information in a table, but it turns out an error, there should be no errors with the syntax, I checked it several times, here is the error itself:



The code itself:

const Canvas = require('canvas')
client.on('guildMemberAdd', async (member) => {
    if (!member.guild) return
    const canvas = Canvas.createCanvas(1772, 633)
    const ctx = canvas.getContext('2d')
    const background = await Canvas.loadImage('./welcome.png')
    ctx.drawImage(background, 0, 0, canvas.width, canvas.height)
    ctx.strokeStyle = '#f2f2f2'
    ctx.strokeRect(0, 0, canvas.width, canvas.height)
    var text1 = `$(member.user.username)`
    var text2 = `$(member.user.discriminator)`
    var text3 = `Участник #$(member.guild.memberCount)`
    var text4 = `$(member.guild.name)`
    if (text1.length >= 14)
    {
        ctx.font = 'bold 100px Sans-Serif'
    ctx.fillStyle = '#f2f2f2'
    ctx.fillText(text1, 720, canvas.height / 2 + 20)
    }
else
{
    ctx.font = 'bold 150px Sans-Serif'
    ctx.fillStyle = '#f2f2f2'
    ctx.fillText(text1, 720, canvas.height / 2 + 20)
}
//Дискриминатор
ctx.font = 'bold 40px Sans-Serif'
ctx.fillStyle = '#f2f2f2'
ctx.fillText(text2, 730, canvas.height / 2 + 58)
// Участники
ctx.font = 'bold 60px '
ctx.fillStyle = '#f2f2f2'
ctx.fillText(text3, 750, canvas.height / 2 + 135)
// гильдия
ctx.font = 'bold 60px Sans-Serif'
ctx.fillStyle = '#f2f2f2'
ctx.fillText(text2, 700, canvas.height / 2 - 150)

ctx.beginPath()
ctx.arc(315, canvas.height / 2, 250, 0, Math.PI * 2, true)
ctx.closePath()
ctx.clip()

const avatar = await Canvas.loadImage(member.user.displayAvatarURL({format:'jpg'}))
ctx.drawImage(avatar, 65, canvas.height / 2 - 250, 500, 500)
const attachment = new DiscordJS.MessageAttachment(canvas.toBuffer(), 'welcome-image.png')
const welcome = new DiscordJS.MessageEmbed()
    .setColor('RED')
    .setTimestamp()
    .setImage('attachment://welcome-image.png')
    .attachFiles(attachment)
const channel = member.guild.channels.cache.find(ch => ch.id === '856761217834418178')
channel.send(welcome)
    })

the reason is that you need to learn the language before writing bots.
