[BUG] ff1.get_session not working

[lalutir]

Describe the issue:

I tried loading data using the get_session function, however, it gives me an error saying failed to load any schedule data.

Reproduce the code example:

fp1 = ff1.get_session(2021, 1, 'FP1')

Error message:

logger      WARNING 	Failed to load schedule from FastF1 backend!
req            INFO 	No cached data found for season_schedule. Loading data...
_api           INFO 	Fetching season schedule...

I think that clearing the content of your FastF1 cache directory should fix the problem.
Apart from that, have you updated to the latest version?

[lalutir]

I already cleared the cache (just deleted the files, found out later there's a function for it) and I am updated to the latest version.

Interesting. Can you post the output with log level set to "DEBUG"?
