An error occurs when you try to store data and make it a Sankey chart.
I don't know why.
Is it simply because the data types do not match?
Thank you.
df = pd.read_gbq (query, 'business-intelli-0099')
from ipysankeywidget import SankeyWidget
SankeyWidget (links = df.to_dict ('records'))Error details
