Puppeteer: BiDi does not support 'omitBackground'.
BiDi screenshots reject omitBackground: true.
BiDi screenshots reject omitBackground: true.
Error message
BiDi does not support 'omitBackground'.
How this error happens
The selected page uses WebDriver BiDi, but the screenshot call requests a setting that this implementation rejects.
Use a page named page from a browser connected with protocol: "webDriverBiDi".
await page.screenshot({
omitBackground: true,
});
How to fix
Omit omitBackground for a normal BiDi screenshot. Use Chrome/CDP if transparent-background capture is required.
await page.screenshot({
type: "png",
});
Things to keep in mind
A normal screenshot is not equivalent to a transparent screenshot. Removing the option changes the image’s background semantics.
