Test does not work with OCI repositories

[tropnikovvl]

I'm using this project and the test fails on it. Flux docs.

flux-local test --path clusters/my-cluster --enable-helm -v

E           flux_local.exceptions.HelmException: Command 'helm template harbor-project-proxy oci://ghcr.io/hiddenmarten/harbor-project-proxy --namespace harbor --skip-crds --skip-tests --version 0.0.1 --values /var/folders/dr/8ck5qq7x1qs12dr6ccwjq2280000gn/T/tmp5ob58gxn/harbor-harbor-project-proxy-values.yaml --registry-config /dev/null --repository-cache /var/folders/dr/8ck5qq7x1qs12dr6ccwjq2280000gn/T/tmpnz52qm_3 --repository-config /var/folders/dr/8ck5qq7x1qs12dr6ccwjq2280000gn/T/tmp5ob58gxn/repository-config.yaml' failed with return code 1

Do you have a helm template command that works for this repository? It gets a 403 Forbidden in the example, so are you expecting this to work without any secrets/permissions?

There seems to be some problem with this repository. I will contact the owner and describe the situation.

In any case, I was able to reproduce the helm template on another OCI helm chart, but unfortunately, to do this I needed to log into my Github account. I haven't found a workaround yet to avoid this.

echo $GITHUB_TOKEN | docker login ghcr.io -u tropnikovvl --password-stdin

helm template oci://ghcr.io/stefanprodan/charts/podinfo

I don't seem to need any credentials:

I checked everything carefully again and this functionality works. There are some problems on my side and on the creator of the chart I mentioned. Thanks for the help! Issue can be closed
