An error occurred: Unable to create the installed package for the package "<package-name>" using the plugin "helm.packages": permission_denied: Missing permissions internal: Unable to fetch the chart <chart-name> from the namespace "kubeapps": calling GetChart '<chart-name> - <chart-version>' without any tarball url.

[ILZ1105]

Describe the bug
This bug appears for all our Habror packages whenever we try to finally deploy the package or upgrade it. We can select the values so it fetches the chart properly but we can not deploy or upgrade it.

To Reproduce
Attach any Harbor OCI Repo. The Repo can even be set to public (no authentication).
Wait for charts to be loaded via cronjob.
Deploy the respective chart.
Dial in any values and hit deploy.

Expected behavior
The chart is deployed.

Screenshots
None, it's a popup that appears after hitting deploy.

Desktop (please complete the following information):

• Version [2.12.1]
• Kubernetes version [1.30.0]
• Package version [17.1.1]

Additional context
This doesn't happen on version 2.11 and lower, however there we have the issue as described in:
