As reported in helm/helm#13466, this problem stems from how the helm ... --repo ... command handles an index.yaml file containing OCI URLs.

Why is this issue appearing now?

Historically, Bitnami Helm charts were accessed by adding the Bitnami repository to the Helm CLI:

$ helm repo add bitnami https://charts.bitnami.com/bitnami

or by directly installing/pulling a specific Helm chart using the --repo flag:

$ helm pull --repo https://charts.bitnami.com/bitnami foo

In April 2023, Bitnami introduced support for the OCI format, recommending OCI-based installation as the primary method going forward. For example:

helm pull oci://registry-1.docker.io/bitnamicharts/external-dns --version 8.6.0

As detailed in our recent announcement and #30110, the traditional method is now being deprecated. Consequently, the index.yaml served at https://charts.bitnami.com/bitnami now uses OCI URLs, exposing the above mentioned issue in the Helm CLI's handling of these URLs.

thx a lot. I have changed the repo url to registry-1.docker.io/bitnamicharts which worked fine.
