Unable to Retrieve Credentials When Installing Apollo Router Helm Chart via OCI

[light-speak]

Describe the bug

When attempting to install the Apollo Router Helm chart using OCI, the command fails with an authentication-related error, even though the chart is publicly accessible.

To Reproduce

Steps to reproduce the behavior:

1. Ensure Helm is installed and supports OCI (e.g., Helm version >= 3.8.0).

2. Run the following command:

   helm upgrade --install -n koskos-staging router oci://ghcr.io/apollographql/helm-charts/router -f ./router-values.yaml
   

3. Observe the error message.

Expected behavior

The Helm chart should install successfully without requiring credentials, as it is publicly available on GHCR.

Output

Error message:

Error: GET "https://ghcr.io/v2/apollographql/helm-charts/router/tags/list": unable to retrieve credentials

Desktop (please complete the following information):

• OS: macOS 15.1.1 (24B91)
• Helm Version: v3.16.2

Additional context

• Docker was logged out from ghcr.io to avoid conflicts.
• Tried helm show values oci://ghcr.io/apollographql/helm-charts/router and received the same error.
• Network connectivity to ghcr.io was verified and works as expected via curl.
