Creating an AzureML environment with a base image from a private repository and publishing to registry fails

[OriolVF]

Operating System

Windows

Version Information

azure-cli: 2.65.0
azure-cli-core: 2.65.0
azure-cli-telemetry: 1.1.0
extensions:
acrquery: 1.0.1
ml: 2.31.0

Steps to reproduce

1. Generate a yaml environment definition:
   $schema: https://azuremlschemas.azureedge.net/latest/environment.schema.json
   name: uritomltable-environment
   image: myacr.azurecr.io/azuremlbuild/myimage:1
   description: Environment created from a Docker image
   version: 1
2. Verify authentication to registry: User can do acr login and docker pull myacr.azurecr.io/azuremlbuild/myimage:1 (authentication works)
3. Create the environment on a registry running az ml environment create --file myenv.yml --registry-name MyRegistry

Expected behavior

Environment is created and pushed to registry. Authentication should work if the user/service principal has rights to the acr and registries.
Extra taken steps:

Actual behavior

Error is returned : Authentication failed for container registry myacr. Code: UserError

Addition information

When trying to publish the environment to a workspace it works fine.
When trying to publish an environment to the registry with an image from an open registry (for example pytorch) it works fine.
