argo-cd: unable to pull helm charts from oci registry (InvalidSpecError)

If you are trying to resolve an environment-specific issue or have a one-off question about the edge case that does not require a feature then please consider asking a question in argocd slack channel.

• I’ve searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• I’ve included steps to reproduce the bug.
• I’ve pasted the output of argocd version.

Describe the bug

When attempting to pull a chart from aws ecr, i receive the following helm error

Unable to save changes: application spec is invalid: InvalidSpecError: Unable to get app details: rpc error: code = Unknown desc = `helm chart pull https://<account id>>.dkr.ecr.<region>.amazonaws.com/helm-charts/appname:2.0.2` failed exit status 1: Error: ref may only contain a single colon character (:) unless specifying a port number

It looks like argocd is construction the wrong syntax for the helm chart pull command. I can reproduce the error from my terminal using a dummy registry (removing any reference to aws)

helm chart pull https://my-example-reg.example-registry/myapp:1.0.0
Error: ref may only contain a single colon character (:) unless specifying a port number

To Reproduce

• Add repo to argocd with oci support
• Confirm the repo exists within argocd, with oci enabled.
• Update an existing application definition use the oci repo. Example of my config below;

project: default
source:
  repoURL: https://<aws_account_id>.dkr.ecr.<region>.amazonaws.com # replace with amazon account and region
  targetRevision: 0.2.0
  plugin:
    name: not-important-info
    env:
      - name: my-env-var
        value: test-var
  enableOCI: true
  chart: helm-charts/my-app
destination:
  namespace: test
  name: test-cluster
syncPolicy:
  automated:
    prune: true
    selfHeal: true

On save, you will receive the error reported above.

Expected behavior

The application definition should successfully update app definition, and pull chart from aws ecr.

Version
