Failed to add machine from MAAS using machine's FQDN (known in MAAS)

[gboutry]

Description

I'm failing to use model.add_machine to add a machine known to MAAS to a model hosted on controller connected to a MAAS cloud. (controller has been bootstrapped to the MAAS cloud even)

Error:

machine = await model.add_machine(spec="sb-n1.maas", series="jammy")
Traceback (most recent call last):
  File "/usr/lib/python3.10/concurrent/futures/_base.py", line 458, in result
    return self.__get_result()
  File "/usr/lib/python3.10/concurrent/futures/_base.py", line 403, in __get_result
    raise self._exception

ValueError: Error adding machine: invalid model name "sb-n1.maas"

Reproduce / Test

from juju.controller import Controller

controller = Controller()
await controller.connect(
                endpoint=<endpoints>,
                cacert=<ca>,
                username=<user>,
                password=<password>,
            )
model = await controller.get_model("openstack-machines")
machine = await model.add_machine(spec="sb-n1.maas", series="jammy")
print("Machine created: {}".format(machine.entity_id))

I have been able to workaround the bug using:

machine = await model.add_machine(spec=model.uuid+":sb-n1.maas", series="jammy")
