FYI v12.4 failed to deploy https://github.com/anthropics/anthropic-sdk-csharp/actions/runs/21724467969/job/62662729880 . Nuget is still on v12.3

Thanks.. I just checked but it still didn't deploy correctly. Looking at the code of the action and the response something's gone bad. No release have been created and subsequent steps were skipped.

code needs releases

if (data?.releases?.length) {
    core.setOutput('releases_created', true);
    outputReleases(data.releases);
  }

response.data has no releases

API Response {

Sorry about that, should be good now (uploaded successfully and I can confirm the version number updated on NuGet)
