List index out of range

Since prev. version I am not able to use the component any more. I am getting this error

When is the next time there is a school lesson?

Has anything changed with version v0.3.1?

[rschueler]

It is possible, that the service does not provide any lessons right now, because in the app there´s also only the next day visible and currently there is nothing, because it is weekend.

After upgrading to 0.3.1 the error changed to:

Traceback (most recent call last):
  File "/usr/local/lib/python3.10/site-packages/webuntis/utils/datetime_utils.py", line 47, in _format
    int(obj)  # is this already formatted?
TypeError: int() argument must be a string, a bytes-like object or a real number, not 'NoneType'

During handling of the above exception, another exception occurred:

That is what i was thinking. Perhaps your school is limiting you to only see the next day. I will try to catch the error so it is not making trouble.

fixed error in v0.3.2
