"Can't specify network Ids in Basic zone" without any network id given

[floek]

Hi,

I get the following error when I use a "Basic Zone" offering, when I have no network id specified.
Other offerings work well.

==> default:  -- Display Name: myshinyvm
==> default:  -- Service offering: XS (c234ef58-24c0-4d15-882e-8345e299e854)
==> default:  -- Template: Ubuntu18.04 bionic (39978996-58e1-4251-9648-3b6789f36a41)
==> default:  -- Zone: Basic_Zone (f4ea2339-e9df-2387-bc62-2f575a3d478b)
==> default:  -- Network:  ()
==> default:  -- Keypair: mysecurekeypair
==> default:  -- Security Group: mysecuritygroup (7fb73293-33ff-479a-82a3-ac46f6232c65)
There was an error talking to Cloudstack. The error message is shown
below:

Can't specify network Ids in Basic zone

Are there any suggestions?

Greetings
