Length mismatch: Expected axis has 33 elements, new values have 6 elements

[a-schiffer]

from wetterdienst.provider.dwd.mosmix import DwdMosmixRequest, DwdMosmixType
allstations = DwdMosmixRequest(parameter='small', mosmix_type=DwdMosmixType.SMALL, start_date='2023-06-23', end_date='2023-06-25')
stations = allstations.filter_by_station_id(station_id=['K2920'])

This code worked fine until six hours ago. Now the last command ("filter_by_station_id()") throws the exception "Length mismatch: Expected axis has 33 elements, new values have 6 elements". I assume that the DWD data format has changed slightly.

The call stack is

  File "wetterdienst\core\timeseries\request.py", line 641, in filter_by_station_id
    df = self.all().df
  File "wetterdienst\core\timeseries\request.py", line 621, in all
    df = self._all().copy().reset_index(drop=True)
  File "wetterdienst\provider\dwd\mosmix\api.py", line 510, in _all
    df.columns = [
  File "pandas\core\generic.py", line 5915, in __setattr__
    return object.__setattr__(self, name, value)
  File "pandas\_libs\properties.pyx", line 69, in pandas._libs.properties.AxisProperty.__set__
  File "pandas\core\generic.py", line 823, in _set_axis
    self._mgr.set_axis(axis, labels)
  File "pandas\core\internals\managers.py", line 230, in set_axis
    self._validate_set_axis(axis, new_labels)
  File "pandas\core\internals\base.py", line 70, in _validate_set_axis
    raise ValueError(
ValueError: Length mismatch: Expected axis has 33 elements, new values have 6 elements

I hope you can reproduce and fix it. Thanks in advance.

Same error message here for different input of stations. Is there a work around until we get a fix?

I also got the same error message:

ValueError: Length mismatch: Expected axis has 33 elements, new values have 6 elements

For me it is already working again. I guess it was some issue @ DWD.

For me, it fails 3 or 4 times with the mentioned exception, then it works again once or twice, but after that it starts failing again...

Hi. We did not find time to investigate yet, but from your reports, it indeed sounds like an intermittent issue. For some of you, clearing the cache may resolve the issue thoroughly. Please let us know if it keeps persisting. Thank you.

The problem didn't show up anymore in the last two days...

@a-schiffer lucky us! We had few situations where the schema of the station listing changed in the past and we would obviously try to push an updated version of wetterdienst that respects the new schema asap! Thanks for reporting anyway! Closing this for now.
