Error when creating a slice

Hello,

Before the updates to the testbed, this code worked:

slice_name = 'test' # create slize
slice = fablib.new_slice(name=slice_name)

vm_names = ['p4switch', 'master']
for vm_name in vm_names:
    node = slice.add_node(name=vm_name, site='RUTG', image='default_ubuntu_20')
    node.set_capacities(cores=2, ram=6, disk=10)
    node.add_component(model='NIC_Basic', name='if1')

p4_node = slice.get_node('p4switch')
for i in range(2, 13):
      p4_node.add_component(model='NIC_Basic', name=f'if{i}')

bridges = {}
bridges['ms'] = slice.add_l2network(name=br)
bridges['ms'].add_interface(p4_node.get_interface('p4switch-if1-p1'))

Now it fails with an error:

Exception: Interface not found: p4switch-if1-p1

The error is fixed by replacing variable p4_node with slice.get_node(‘p4switch’) at the last line (basically, re-fetching the node). Why would I get the error without this change? Thank you.
