Lap and Telemetry data for 'Pre-Season Testing 2024'

[FormulaNeon]

Hi everyone, I was wondering if anyone else is encountering this error or whether there's something wrong that I am doing.
I'm trying to load data for pre-season testing

print(fastf1.__version__)
print(platform.python_version())

3.3.0
3.10.4

session = fastf1.get_session(2024, 'Pre-Season Testing','Practice 1')
session.load()
