TypeError: Expected tuple, got str

When querying generation for Denmark and Slovenia (all other countries seem to work as expected) since 01/01/2016, i am encountering the following error using the pandas client:

client.query_generation('DK', start=pd.Timestamp('201601010000').tz_localize(area_mapping['DK'].tz), end=pd.Timestamp('202201010000').tz_localize(area_mapping['DK'].tz)).to_csv('DK_generation_per_type.csv')

Any insight would be much appreciated
Thanks

hi @polsinello thank you for your repport. thats really strange and a bit puzzling to me. Could you perhaps compare the xml output for slovenia with another country that doesnt have this problem? this seems to me like an issue with weird api response
