Hi', in my

Pulumi.env.yaml

I have declared:

config:
  tools:data:
    vpn:
      vm:
        name: servername
        size: Standard_D4s_v2
    registry:
      config:
        name: registryname

then from my

___main___.py

cfg = pulumi.Config().require_object('data')
vm = cfg.get('vpn').get('vm')
registry = cfg.get('registry').get('config')

later on when I use such var

vm = azure_native.compute.VirtualMachine(
  "vpn-VirtualMachine",
  hardware_profile=azure_native.compute.HardwareProfileArgs(
   vm_size=config.vm.get('size'),
  ),
# ...

everything works, but when I use

registry = azure_native.containerregistry.Registry(
  "container-Registry",
  admin_user_enabled=True,
  location=config.region,
  registry_name=config.registry.get('name'),

even if it sees to be the same logic, I'm getting this error:

File "/<MY_PATH>/venv/lib/python3.8/site-packages/pulumi/runtime/stack.py", line 181, in massage
        if not key.startswith("_"):
    TypeError: startswith first arg must be bytes or a tuple of bytes, not str
    error: an unhandled error occurred: Program exited with non-zero exit code: 1

any idea of what I'm doing wrong?
