Canvas error when using toCanvas()

Shortened code snippet:

const view = new vega
    .View(vega.parse(chartData))
    .renderer('none')
    .initialize()
view
    .toCanvas()
    .then(canvas => {
        consle.log('Generating image...!')
        fs.writeFile('./growth.png', canvas.toBuffer(), () => {
         // Handling
        })
    })

Full error log:

To fix this, I’ve tried:

• Reinstalling all dependencies in my project (including canvas, vega, fs, node-pre-gyp)
• Using various node versions
• Using various canvas versions

This identical error persists no matter the case, seeking some help.

Node version: 12.18.3 NPM version: 6.14.7 Vega version: 5.13.0 Canvas version: 2.6.1

Same error on Win 10, npm ci resolved the issue

Hmm, I don’t know about windows but our tests are running on ubuntu. Could you take a look at https://github.com/vega/vega/blob/master/.github/workflows/test.yml and see whether the build steps help you?
