Cannot read property 'packages' of null

[ovidals]

Hi!

I'm using the following code to remove old versions from another repository wich is private:

 - uses: actions/delete-package-versions@v1
    with:
      owner: '---'
      repo: '---'
      package-name: '---'
      num-old-versions-to-delete: 1
      token: ${{ secrets.CI_PACKAGES_READ_DELETE_TOKEN }}

I have created a personal access token with read and write packages permissions and stored as secret on the repository that is firing the action, but this error is thrown:

Cannot read property 'packages' of null

Any help on this?

Thank you!

Happens for me too when I use ghcr.io (https://docs.github.com/en/packages/getting-started-with-github-container-registry/migrating-to-github-container-registry-for-docker-images)

With this change images are now stored at org level and not package level, maybe this is causing the error

Looks like this is the problem as only repository packages are fetched using graqhQL

delete-package-versions/src/version/get-versions.ts

Line 29 in 35f1b74

packages(first: 1, names: [$package]) {

Have the same issue, @firefart do you know how to query the new ghcr stored versions ?
I used the GraphQL explorer but I do not seem to find any Docker packages, which I have on my private user.
I also found this information regarding the registry: https://github.community/t/ghcr-io-docker-http-api/130121
Maybe we can extend the current functionality to fetch from ghcr and then delete from there as well, and open a PR.
I Have the same use case as @ovidals

Facing almost the same issue using ghcr.io:
Error: TypeError: Cannot read property 'node' of undefined

After searching some more I also found this Info:
https://github.community/t/github-container-registry-ghcr-io-packages-not-appearing-in-api/130133
Basically there is no ETA when the GraphQL API will also give out/handle container images,
which would enable this action to almost directly work.

I also tried the docker catalog api directly, hoping we could implement it ourselves:
ghcr.io/v2/<owner>/<image>/tags/list
but it, with all permissions, just returns:
{ "errors": [ { "code": "DENIED", "message": "invalid token" } ] }

So the only way currently is the GH Frontend which can list/delete the images.
Well currently as far as I can tell is, that all we can do is wait.
The GH public roadmap also seems not to have much coming up for ghcr.

Interesting quote from Staff very recently:

But we’re working on a delete API that could be used on PR merge. Hoping to have this out by end of month.

So there was an update on: https://github.community/t/are-there-plans-to-support-deletions-of-images-in-ghcr/153728
which now offers the v3 REST API to list and delete containers from ghcr.io:
https://github.community/t/you-can-now-delete-and-restore-any-package-type-within-github-packages/162393

So I did a very rough integration to proof it is working:
main...kc1r74p:main

I used my fix version like this:

        name: Remove previous version
        uses:  kc1r74p/delete-package-versions@main
        with:
          owner: ${{ github.repository_owner }}
          package-name: '<package_name>'
          package-type: 'container'
          ignore-tag: 'latest'
          token: ${{ secrets.CR_PAT }}

I could try to get a PR going for this repo, just not sure if GraphQL will implement containers in the future which would deprecate this kind of fix.
@andymckay Could we get your opinion, might help to decide if we should integrate it or wait further.

Might also solve: #35
