Wetterdienst Explorer on streamlit.app is not working for some parameters/networks

[SB-511]

Describe the bug
On https://wetterdienst.streamlit.app/ with some parameter combinations I get a red error message instead of the selected data.

To Reproduce

I tried with several parameter combinations, e.g.:

• DWD | MOSMIX | small | small | ...
• DWD | ROAD | minute_10 | minute_10 | any
• DWD | Observation | daily | precipitation_more | precipitation_height | NOW

It works well with e.g.:

• • DWD | Observation | minute_10| precipitation | precipitation | NOW

Expected behavior
Showing data :)

Dear @SB-511 ,

thanks for reporting!

1. DWD Mosmix was an actual issue with the setup of the request kwargs. DWD Mosmix and DMO have to be handled differently as they don't really have resolution. It should work for now with the new version - v0.94.0 was just released -but I will add some test the other day.
2. DWD Road I still have to look into. Probably I didn't correctly drop it and it shouldn't be there at all as it requires eccodes installed on the system and on streamlit we don't have access to the underlying system at all...
3. This is a bug, the now period is not valid for daily data. Daily data is only being published daily but not more frequently which the now period was crafted for. Will fix that the other day.

Did you have further issues?
