Lighthouse not working anymore

[hjelmdal]

As of december 18th, my release pipeline has failed with a -Lighthouse v7.0 message of bad configuration flags being set. My CLI config is clean, so I am guessing that the extension is injecting something not supported anymore?

Hi @hjelmdal from the logs I can see that your CLI arguments doesn't seem empty. Looks like you've added:

--emulated-form-factor=none --throttling-method=provided --verbose

When I look at your logs, this documentation page is mentioned. --emulated-form-factor have been removed and you muse use --preset instead.

It's true that the extension injects other CLI arguments, but as you can see in the logs, it's only those required to generate an HTML and JSON output as well as running the tool in headless mode. I've tested it with Lighthouse 7 and it works well with empty CLI arguments.
