Incompatibility?

[keesj]

Hello, I am trying to render the following using a pip installed wavedrompy

{signal: [
    {    name: 'clk',        wave: 'p..pp......p'},
    {name: 'input_ready',    wave:    '010.........', node:'............', },
    {name: 'signalanalisys', wave: '0...3....0..'   , node:'............', data: ["running"]},
    {                                                 node:'.A..B.......', },
    {name: 'output_ready',    wave:   '0........10.', },
  
],
  edge: [
    'A<->B delay'
]
}

On the online version this works nicely

But when I tried to render it using wavedrompy (from the command line) I am getting this error:

Traceback (most recent call last):

It appears that wavedrompy can not find the "A" label
