I had the same problem related to: https://blog.bitnami.com/2024/10/bitnami-helm-charts-moving-to-oci.html
Solunion is to change:
repository = "https://charts.bitnami.com/bitnami"
to
repository = "oci://registry-1.docker.io/bitnamicharts"

As @kfkawalec has pointed out, this is because bitnami has switched to OCI for their charts. See here:
