Puppeteer: 'width' in 'clip' must be positive.

Screenshot clip width is zero or negative.

Error message

'width' in 'clip' must be positive.

How this error happens

A screenshot rectangle must have a positive width. A zero-sized region contains no image to capture.

The snippets use an open Puppeteer page named page.

await page.screenshot({
    clip: {
        x: 0,
        y: 0,
        width: 0,
        height: 480,
    },
});

How to fix

Use a positive width and validate calculated dimensions before passing them to Puppeteer.

await page.screenshot({
    clip: {
        x: 0,
        y: 0,
        width: 640,
        height: 480,
    },
});

Things to keep in mind

If the dimensions come from an element, wait for its layout rather than substituting an arbitrary size.
