I've successfully pushed some locally built helm chart to harbor private helm registry using below commands:
helm registry login private.harbor.com
helm push chart-version.tgz oci://private.harbor.com/some-project
Now I fail to add helm repo (for the goal of installation of the pushed helm chart) using below commands:
$ helm repo add helm-test2 oci://private.harbor.com/some-project/
Error: looks like "oci://private.harbor.com/some-project/" is not a valid chart repository or cannot be reached: object required
$ helm repo add helm-test2 oci://private.harbor.com/some-project/helm-test-repo
Error: looks like "oci://private.harbor.com/some-project/helm-test-repo" is not a valid chart repository or cannot be reached: object required
$ helm repo add helm-test2 https://private.harbor.com/some-project/helm-test-repo
Error: looks like "https://private.harbor.com/some-project/helm-test-repo" is not a valid chart repository or cannot be reached: error unmarshaling JSON: while decoding JSON: json: cannot unmarshal string into Go value of type repo.IndexFile
$ helm repo add helm-test2 https://private.harbor.com/some-project

How to helm repo add Harbor OCI helm repository?
It's important to note that docker images are stored alongside pushed helm charts at private.harbor.com/some-project/.
Alternative way that worked is uploading helm chart under Helm charts tab in some-project in Harbor UI.
Afterwards, below commands for adding and installing the chart worked:
helm repo add helm-test https://private.harbor.com/chartrepo/some-project
helm repo update helm-test
helm install chart helm-test/chart --version 1.5.0
I would use this method, but have no idea how to push to https://private.harbor.com/chartrepo/some-project, pushing to oci://... worked only after following this github link.
Below attempts failed:
helm push chart-version.tgz oci://private.harbor.com/chartrepo/some-project
Error: unexpected status: 401 Unauthorized
helm push chart-version.tgz https://private.harbor.com/chartrepo/some-project
Error: scheme "https" not supported
I'm using latest helm (3.8) and harbor version (2.5)
