Any update on this issue? I was trying to use the API and at first I shrugged at the example not working. But the same exact error occurs again when I try to use einheit_einheit_json_get_erweiterte_oeffentliche_einheit_stromerzeugung_get() in my own functions.

[linush-vk]

For anyone else facing this issue: I found a workaround using a keyword argument to prevent checking the return type of the data:

api_response = api_instance.einheit_einheit_json_get_erweiterte_oeffentliche_einheit_stromerzeugung_get(
    filter=filter, _check_return_type=False
)
