Puppeteer: Unknown product: {value}

launch receives a browser value other than chrome or firefox.

Error message

Unknown product: {value}

{value} is replaced by the value shown in your error message.

How this error happens

launch supports chrome and firefox. A browser option such as safari does not select an alternative executable.

The snippets use the imported puppeteer instance.

await puppeteer.launch({
    browser: "safari",
});

How to fix

Choose a supported browser. If you use a custom compatible executable, supply its path separately.

const browser = await puppeteer.launch({
    browser: "chrome",
});

Things to keep in mind

An arbitrary browser binary does not become compatible simply because you pass it as executablePath. Close the launched browser after use.
