Hi I am getting the same error when trying to package a chart that has a dependency stored in AWS ECR. Chart.yaml:

apiVersion: v2
name: my-service
version: 0.0.1-SNAPSHOT
description: test service
...
dependencies:
  - name: demo-service
    version: "2.2.6"
    repository: "oci://xxxxxxxxxxxx.dkr.ecr.eu-west-1.amazonaws.com/demo-service"

Error when running helm package my-service/ -u:
