Prune github actions cache

[piomark]

Hi,

I need some help with removing old versions of Cypress in the CI (github actions).
I'm facing issues with cypress binaries getting cached over and over again (we are now on 10.4.0 and I still have bin's from v8).

I know it's possible to prune the cache using cypress cache prune, but if I execute this function after the installation/test execution the cache is not changed.

I've tried to play with custom cache key but it looks like cypress bins are not included in this one.

How I can correctly execute the cache prune?

my workflow:

(...)
- name: Checkout
uses: actions/checkout@v3
- name: Cypress run
uses: cypress-io/github-action@v4
with:
working-directory: "./Tests/UI tests"
record: true
config-file: cypress.config.js
spec: "cypress/envSetup/*"
cache-key: ${{ runner.os }}-hash-${{ hashFiles('Tests/UI tests/package-lock.json') }}
env:
CYPRESS_PROJECT_ID: ${{ secrets.CYPRESS_PROJECT_ID }}
CYPRESS_RECORD_KEY: ${{ secrets.CYPRESS_RECORD_KEY }}
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
DEBUG: "cypress:server:args"
- name: prune cache
if: always()
run: |
npx cypress cache prune
npx cypress cache list
(...)

when my custom prune get's called I have just 1 dll which is correct. The issue is that this cache is not saved.

Thanks,
Piotr
