Research direction

Start with index.js lines 36-68, then compare the documented --lighthouse.config and --lighthouse.flags options with the Chrome flags configured there. Reproduce the PROTOCOL_TIMEOUT against the localhost page and determine whether an additional flag can be passed; done means the supported configuration path is documented or the issue is narrowed to an upstream Lighthouse failure.

Description

Your question

Hi
I'm trying to test pages with sitespeedio/sitespeed.io:25.11.0-plus1
But receiving the error:
ERROR: Lighthouse could not test http://localhost:3000/testPage please create an upstream issue: https://github.com/GoogleChrome/lighthouse/issues/new?assignees=&labels=bug&template=bug-report.yml LHError: PROTOCOL_TIMEOUT
at /lighthouse/node_modules/lighthouse/lighthouse-core/gather/driver.js:348:50.....

After researching, one possible solution that could help is to add a chrome flag "--disable-dev-shm-usage" (https://github.com/GoogleChrome/lighthouse/issues/6512)
But none of the options for passing flags to the lighthouse plugin, as I see it, does not work for me (from --lighthouse.config config.js or --lighthouse.flags flag.json)
And as I see here https://github.com/sitespeedio/plugin-lighthouse/blob/main/index.js#L36-L68 the chrome flags are already set but without the ability to pass additional flags into it (maybe I'm wrong).
@soulgalore could you please tell me if there are any other ways to pass chrome flags to the lighthouse plugin?
Or maybe there are other ways to fix the error?
