polars (pl) ComputeError

[justwannabehero]

Hello dear Community,
I didn't find the question related to this topic and therefore answer, so I would like to ask you here.
I try to get data as from the example code, nothing much, but get an error related to polars library:

import polars as pl
_ = pl.Config.set_tbl_hide_dataframe_shape(True)
from wetterdienst import Settings
from wetterdienst.provider.dwd.observation import DwdObservationRequest
settings = Settings( # default
    ts_shape="long",  # tidy data
    ts_humanize=True,  # humanized parameters
    ts_si_units=True  # convert values to SI units
)
request = DwdObservationRequest(
    parameter=["climate_summary"], # or kl as in original name
    resolution="daily",
    start_date="2017-01-01",  # if not given timezone defaulted to UTC
    end_date="2024-01-01",  # if not given timezone defaulted to UTC
    settings=settings
).filter_by_station_id(station_id=(1048, 4411))
stations = request.df
stations.head()

Error:

     [17](vscode-notebook-cell:?execution_count=4&line=17) stations = request.df
     [18](vscode-notebook-cell:?execution_count=4&line=18) stations.head()

....
ComputeError: conversion from `str` to `f64` failed in column 'height' for 1359 out of 1359 values: ["70101 19860630", "10101 20110331", … "31101 19860930"]

The thing is that yesterday everything worked fine, but today there is this error. And this error appears even on the 'streamlit' (on the screenshot)
Thank you in advance for you help!
