Valve generates error

[watturkara]

When I try to run example code adapted from the MINT wiki, it generates the following error:

Traceback (most recent call last):
  File "//.pyenv/versions/3.8.0/bin/fluigi", line 8, in <module>
    sys.exit(main())
  File "//.pyenv/versions/3.8.0/lib/python3.8/site-packages/fluigi/cmdline.py", line 243, in main
    par_device = generate_device_from_parchmint(str(temp_parchmint_file))
  File "//.pyenv/versions/3.8.0/lib/python3.8/site-packages/fluigi/cmdline.py", line 80, in generate_device_from_parchmint
    return Device(device_json)
  File "/pybin/pyparchmint/parchmint/device.py", line 71, in __init__
    self.parse_from_json(json)
  File "/pybin/pyparchmint/parchmint/device.py", line 296, in parse_from_json
    self._valve_map[self.get_component(key)] = self.get_connection(value)
TypeError: unhashable type: 'Component'

It seems this is an issue with placing Valves in general. Here is the code I ran to generate this error:

  DEVICE net_test
  
  LAYER FLOW
  PORT p1, p2 portRadius=100;
  V LONG CELL TRAP ct1 numberOfChambers=10 chamberWidth=100 chamberLength=100 chamberSpacing=50 feedingChannelWidth=100;
  
  CHANNEL c1 from p1 3 to ct1 1 channelWidth=100;
  CHANNEL c2 from ct1 2 to p2 1 channelWidth=100;
  
  END LAYER
  
  LAYER CONTROL
  PORT p3 portRadius=100;
  VALVE v1 on c1 width=300 length=100;
  VALVE v2 on c2 width=300 length=100;
  NET net1 from p3 1 to v1 4, v2 4 channelWidth=50;
  END LAYER
