[BUG] Error loading LiveData #542

Closed nicZox closed 1 month ago

nicZox commented 4 months ago

Describe the issue:

By loading the data recorded by livetiming, drivers are not found (being None) and making it impossible to use the functionality of FastF1

Reproduce the code example:

livedata = LiveTimingData('2024_Livetiming.txt')
session = fastf1.get_session(2024, 'Bahrain Grand Prix', 'R')
session.load(livedata=livedata)

Error message:

data           INFO     Reading live timing data from recording. This may take a bit.

@theOehrly Is there a possible bypass for this? Without waiting for 3.4.1?

@theOehrly Is there a possible bypass for this? Without waiting for 3.4.1?

I don't know at the moment. I haven't investigated this in depth. I was simply able to reproduce the problem and it clearly looks like a bug. Is there any particular reason why this is important? At the moment, all sessions (including pre-season testing) are available using the "normal" way of downloading the data from the API. Therefore, it's not really that important (short term) because only the fallback method is broken. Or is there something that particularly requires the usage of the recorded live data?
