TableDisplay - AttributeError: 'Series' object has no attribute 'get_values'

Beakerx was working until a few weekly perfect.

The following command shows a beakerx table:
TableDisplay([{'y1':4, 'm3':2, 'z2':1}, {'m3':4, 'z2':2}])

But for a DataFrame it get's the error:
AttributeError: 'Series' object has no attribute 'get_values'

df = ([{'y1':4, 'm3':2, 'z2':1}, {'m3':4, 'z2':2}])
df = pd.DataFrame(df)
TableDisplay(df)
