Azure SDK Container app

Hello community!

I have a problem using the python SDK when trying create a Container app from docker image already up in my ACR.

Im using the ACR administrator credentials (already enabled in Settings > Access key).

My python code look like this:

from azure.identity import ClientSecretCredential

from azure.mgmt.appcontainers import ContainerAppsAPIClient


tenant_id = 'XXXXX'
client_id = 'XXX'
client_secret = 'XXX'

subscription_id = 'XXX'
resource_group = 'resource-group'
environment_name = 'env-name'

version = '1.0.0'
image_name = 'my-api'
acr_name = 'myacrname'
container_app_name='container-name'

docker_registry_username = 'acrname'
docker_registry_password = 'XXX'

client = ContainerAppsAPIClient(
    credential=ClientSecretCredential(
        tenant_id=tenant_id,
        client_id=client_id,
        client_secret=client_secret
    ),
    subscription_id=subscription_id,
)

environment_id = f'/subscriptions/{subscription_id}/resourceGroups/{resource_group}/providers/Microsoft.App/managedEnvironments/{environment_name}'


response = client.container_apps.begin_create_or_update(
    resource_group_name=resource_group,
    container_app_name=container_app_name,
    container_app_envelope={
        "location": "East US",

                    }
                ],
                "secrets": [
                    {
                        "name": "docker-pwd",
                        "value": docker_registry_password  
                    }
                ]
            },

                        "name": container_app_name,
                        "probes": [
                            {
                                "httpGet": {
                                    "httpHeaders": [{"name": "Custom-Header", "value": "Awesome"}],
                                    "path": "/health",
                                    "port": 8080,
                                },
                                "initialDelaySeconds": 3,
                                "periodSeconds": 3,
                                "type": "Liveness",
                            }
                        ]
                    }
                ],
                "revisionSuffix": "cxx",
                "scale": {
                    "maxReplicas": 5,
                    "minReplicas": 1
                },
            },
        },
    },
).result()
print(response.json())

This code returns this error:

(ContainerAppOperationError) Failed to provision revision for container app 'container-name'. Error details: The following field(s) are either invalid or missing. Field 'template.containers.container-name.image' is invalid with details: 'Invalid value: "myacrname.azurecr.io/my-api:1.0.0": GET https:?scope=repository%3Amy-api%3Apull&service=myacrname.azurecr.io: UNAUTHORIZED: authentication required, visit https://aka.ms/acr/authorization for more information.';..

Any ideas?
