Since 31st January our lighthouse reports have been failing when running inside of the femtopixel/google-lighthouse:latest docker image which roughly coincides with the v4.1.0 release. The build hangs for 45 seconds when it is loading the page to test (or longer for however long I set the '--max-wait-for-load' flag. I have tried 5 mins and this still occurs) then once it times out an unhandled error is thrown and the container exits.
Command line I used to start the containerdocker run -it femtopixel/google-lighthouse:latest bash
also occurs when docker image is used within a Jenkins build pipeline using the docker plugin
Steps to reproduce the issue:
run lighthouse https://coolstuff.se --output-path=./se --chrome-flags='--headless --no-sandbox' within the latest docker image
