FAQ

---

* Error while writing files

```

Runtime error encountered: { Error: EACCES: permission denied, open '/home/chrome/reports/myawesome_site_admin_heavypage.report.json'

errno: -13,

code: 'EACCES',

syscall: 'open',

path: '/home/chrome/reports/myawesome_site_admin_heavypage.report.json' }

```

Make sure your folder has the write right for others (chmod o+w)

If the issue still occurs, you may want to add `--disable-shm-dev-usage` Chrome flag (cf. https://stackoverflow.com/questions/69173469/meaning-of-selenium-chromeoptions/69175552#69175552 and https://issues.chromium.org/issues/40517415; thx @kevinbreit - https://github.com/femtopixel/docker-google-lighthouse/issues/25)

You can add this flag with the `-e` flag in your docker command `docker run --rm --name lighthouse -it -e CHROME_FLAGS="--headless --disable-gpu --no-sandbox --ignore-certificate-errors --disable-dev-shm-usage --allow-insecure-localhost --silent" -v /path/to/your/report:/home/chrome/reports femtopixel/google-lighthouse http://www.google.com --output json`
