Telemetry problem

[McHouse]

I am using this code
`for INI in drivers_to_visualize:
laps_Drv = Race_laps.pick_driver(INI)

Nlaps_D = len(laps_Drv)
VMaxA = laps_Drv[['SpeedI1', 'SpeedI2',
                  'SpeedFL', 'SpeedST']].max(axis=1).max()
VMaxAc = VMaxA * 0.001

hora1 = time.time()
pos += 1
print(pos, INI)
Piloto_FA = {}
Piloto_PC = {}
Driver = {}

for i in range(1, Nlaps_D+1):
    lap = laps_Drv[laps_Drv['LapNumber'] == i]
    telemetry = lap.get_telemetry()`

with version 3.1.6 of fastf1 it doesn't give me any problems.
But with version 3.3.0 it gives me:
v3.py:455
telemetry = lap.get_telemetry()

File ~\anaconda3\envs\FF1_V330\lib\site-packages\fastf1\core.py:2732 in get_telemetry
pos_data = self.get_pos_data(pad=1, pad_side='both')

File ~\anaconda3\envs\FF1_V330\lib\site-packages\fastf1\core.py:2807 in get_pos_data
pos_data = self.session.pos_data[drv_num] \

AttributeError: 'NoneType' object has no attribute 'pos_data'

What am I doing wrong, or not doing?

Thanks in advance

OK! I already saw it.

With some small changes, I'd better use this
df = laps.pick_driver(INI).pick_lap(VuNum).telemetry

Works.
