[Help] Setup looks good, but still downloads cache from external source

[MarcARoberge]

Hello! I just need some help/support. I am configuring this server on Mac OS and everything looks good except when I run the setup-node actions with the cache: npm option, it stills downloads it from an outside source.

This is an echo of the env.ACTIONS_CACHE_URL for this job (looks good).

And here's what it looks like when using the setup-node actions

Any idea why it acts like that? Any clue to where to look ?

How are you setting the ACTIONS_CACHE_URL and did you modify the runner binary so it actually uses the custom ACTIONS_CACHE_URL?

[MarcARoberge]

This is the step:

 - name: Set up secret file
        env:
          ACTIONS_CACHE_URL: ${{ secrets.ACTIONS_CACHE_URL }}
        run: |
          echo ${{env.ACTIONS_CACHE_URL}} | sed 's/./& /g'

Have a look at this https://gha-cache-server.falcondev.io/getting-started#getting-the-actions-runner-to-use-the-cache-server

I did try it, but since I am on Mac it looks like I needed some changes, if not I would get a illegal byte sequence error. Here's the command I did:

 LC_ALL=C sed -i '' 's/\x41\x00\x43\x00\x54\x00\x49\x00\x4F\x00\x4E\x00\x53\x00\x5F\x00\x43\x00\x41\x00\x43\x00\x48\x00\x45\x00\x5F\x00\x55\x00\x52\x00\x4C\x00/\x41\x00\x43\x00\x54\x00\x49\x00\x4F\x00\x4E\x00\x53\x00\x5F\x00\x43\x00\x41\x00\x43\x00\x48\x00\x45\x00\x5F\x00\x4F\x00\x52\x00\x4C\x00/g' ./actions-runner-6/bin/Runner.Worker.dll

Can you try running the action with debug logs enabled. It should print out the url it is downloading cache from.

[LouisHaftmann]

Have you tried setting the ACTIONS_CACHE_URL env var when running the actions runner, not inside the workflow file:

ACTIONS_CACHE_URL=<url> ./run.sh

[MarcARoberge]

From what I can see from debug is that it is evaluating the secrets.ACTIONS_CACHE_URL but looks like it is still the Github's one. I'll try to find something else with the sed command that might caused that.

Update: using gsed on Mac OS seems to give a better result.

UPDATE 2: I was missing a /. Trying with gsed

Ok really good progress done. Looks like everything is setup, but I am receiving a error 500 since it looks like the cache is too big (around 5gb).

From what I understand, Buffer.alloc has a size limit. What can we do from here? Thinking maybe doing chunks?

Should be fixed in v2.1.0
