Expected behavior

Code running without errors.

Current behavior

When executing code, the following error occurs :

Uncaught TypeError: element.ownerDocument.defaultView is null
    getComputedStyle helpers.segment.js:2161
    getStyle helpers.segment.js:2163
    readUsedSize helpers.segment.js:2351
    initCanvas chart.js:3227
    acquireContext chart.js:3381
    Chart chart.js:5602

None

Optional extra steps/info to reproduce

No response

Possible solution

Rewrite the function getComputedStyle in "chart.js/dist/chunks/helpers.segment.js:2161" as follow :

const getComputedStyle = (element)=>element.ownerDocument.defaultView?.getComputedStyle(element, null) ?? { getPropertyValue: () => null };

Context

I had a code that worked, then I upgraded Chart.js npm package.

chart.js version

v4.3.0

Browser name and version

Firefox 113.0.2 / Chromium 114.0.5735.106

Also running into this issue with the desktop GUI framework, Sciter.js

Downgrading to 3.x fixed it.
