Contributor guide
Research direction
Start by reproducing the report in Chrome DevTools with Lighthouse 11.1.0 using the ratemds.com URL from the issue. Inspect the Target.attachToTarget error and the provided Puppeteer connection stack trace; done means Lighthouse produces a report instead of the reported protocol error.
