Description

Running this tutorial notebook locally fails (see error message below). I expected to see this table:

What I Did

When running the tutorial notebook from top to bottom, this example

# get data for all Bundesländer
query_all = Query.all_regions(nuts=1)
query_all.add_field('BEV001')
query_all.results().sort_values('year').head(12)

raises this error:
