Enabling DHCP on tagged vlan causes primary rack selection error

[artscout]

  We're using this code for adding vlan and subnet to maas (it's already enabled on maas machine interfaces)

    prefix = "192.168.130.0/24"
    ip_network = ipaddress.ip_network(prefix, strict = False)
    vlan = "2001"
    maas_vlan = fabric.vlans.create(vlan)
    maas_subnet = self.client.subnets.create(prefix, maas_vlan, gateway_ip = str(ip_network[-2]))
    half = ip_network.num_addresses / 2                                                       
    range_start = str(ip_network[int(half)])                                                  
    range_end = str(ip_network[-6])                                                           
    new_range = self.client.ip_ranges.create(range_start, range_end, type=IPRangeType.DYNAMIC)
    range_vlan = maas_subnet.vlan                                                             
    rack = self.client.rack_controllers.list()[0]
    range_vlan.primary_rack = rack
    range_vlan.dhcp_on = True
    range_vlan.save()

Execution of this code returns this:

yfkq88 is valid rack controller ID BTW, it's the only rack controller in whole setup.

Any ideas?
