How to load images in express js hosted on vercel-CodePudding

I am trying to make a GitHub banner generator using express js, my code works fine locally but when I try to host it on vercel all the image files go missing and I get no such file or directory found error.

app.get('/api',async(req,res)=>{

    const title = req.query.title || "Github Banner Generator"
    const subTitle = req.query.subtitle || ""
    
    const theme = req.query.theme || "default"

    const _theme = require(`./themes/${theme}/${theme}.json`)

    const image = await loadImage(fs.readFileSync('themes/default/image1.png'))

    const img = await new Canvas(1280, 520)
    .printImage(image,0,0)
    .setColor(_theme.primaryColor)
    .setTextFont('bold 60px Serif')
    .setTextAlign('center')
    .printText(title,1280/2,520/2)
    .setTextFont('20px Serif')
    .setTextAlign('center')
    .printText(subTitle,1280/2,(520/2) 60)
    .toBuffer();

    res.set({'Content-Type':'image/png'})
    res.send(img)
})

I think the image path isn't right.

Maybe you could try this...

const image = await loadImage(fs.readFileSync(__dirname 
  '/themes/default/image1.png'));
