This fails on Vercel as it pushes serverless bundle over 50mb. (Read more here)

I've found installing these versions of the packages put us under this limit.

npm i --save chrome-aws-lambda@^8.0.2 puppeteer-core@^8.0.0

As an addition to @Otoris 's comment.

If you are also using lighthouse with this combo, you still hit the wall, using these versions keeps me under 50mb;

    "chrome-aws-lambda": "^6.0.0",
    "lighthouse": "^6.1.1",
    "puppeteer-core": "^6.0.0"
