typescript - How can I send uploaded image as sticker in Telegram? (Telegraf Library)

Question

I want to send uploaded image as sticker in channel. I can't find any source for this. It's my code:

ctx.telegram.getFileLink(photo.file_id).then(url => {    
    axios({url, responseType: 'stream'}).then(response => {
        response.data.pipe(fs.createWriteStream(`images/public/images/${photo.file_id}.png`))
        .on('finish', async() => {
           ctx.replyWithSticker({source: `images/public/images/${photo.file_id}.png`})
        })
        .on('error', (e: Error) => { 
           ctx.reply("An error occured")})
        })
    })
})

But it sending me this:

Image

Can someone help me? Thanks.
