Incognito Lighthouse performance issues

Question

I am getting this issue while running a performance test.

The suggestions is to run it in incognito, but I am running it in incognito and still getting this issue.

It is still running the test and giving me a score, but it seems something is affecting.

There were issues affecting this run of Lighthouse: There may be stored data affecting loading performance in this location: IndexedDB. Audit this page in an incognito window to prevent those resources from affecting your scores.

Answer 1

I managed to clear this message by going in to the "Application" tab in Inspector and clicking "Clear site data" and then rerunning the Lighthouse test.

EDIT: spoke too soon... It seemed to clear it the first time and then the 2nd time I tried to re-run the test I got the same warning message. Perhaps it's not clearing everything?

The problem persists. Tried it today and the warning is still there. – Appenzell

Answer 2

i face the very same issue:

site data showed some amount of data in indexdb although indexdb itself appears empty when i investigate it by clicking the node. after clearing site data indexdb went to 0 ad everything appears cleared. the alert remains unchanged.

when running lighthouse in incognito mode the alert is not there, so that hint at least works fine on my machine.
