Slider does not update frame on plot

Hello, I’m trying to update the plotted frames based on the slider. Even though the slider updates, the data on the graph doesn’t. Any ideas?

  # Create figure
  figure = {
    'data': [{
      'type': 'bar',
      'x': list(srt.np.linspace(0, len(arr), num=len(arr))),
      'y': arr
    }],
    'layout': {
      'xaxis': {
        'title': 'X',
        'gridcolor': '#FFFFFF',
        'linecolor': '#000',
        'linewidth': 0,
        'zeroline': False,
        'autorange': True
      },
      'yaxis': {
        'title': 'Y',
        'gridcolor': '#FFFFFF',
        'linecolor': '#000',
        'linewidth': 0,
        'autorange': True
      },
      'title': method,
      'updatemenus': [{
        'type': 'buttons',
        'buttons': [{
          'label': 'Play',
          'method': 'animate',
          'args': [None, {
            'frame': {
              'duration': 10,
              'redraw': True
            },
            'fromcurrent': True,
            'transition': {
              'duration': 30,
              'easing': 'quad-in-out'
            }
          }]
        }]
      }]
    },
    'frames': []   
  }

  # Add slider
  sliders = [dict(steps=[
    dict(method='animate', args=[[k], dict(
      mode='e', frame = dict(duration=50, redraw=False), transition=dict(duration=0)
      )],
      label=k) for k in range(len(frames))],
      transition=dict(duration=30),
      x=0,
      y=0,
      len=1.0,
      active=0,
      currentvalue=dict(font=dict(size=12), 
                        prefix='Step: ', 
                        visible=True, 
                        xanchor= 'center')
    )]
  
  figure["layout"]["sliders"] = sliders

  # Update frame
  for k in range(len(frames)):
    frame = {"data": {
      'type': 'bar',
      "x": list(srt.np.linspace(0, len(arr), num=len(arr))),
      "y": frames[k]
    }}
    figure["frames"].append(frame)

  fig = go.Figure(figure)

Could you please provide a standalone code (ie with all variables defined, eg synthetic variables, and packages imported)? It would make it easier to reproduce your problem.
