Violinplot works but swarmplot throws keyerror

[Casper-Guo]

I have a dataframe obtained from Fastf1 and I want to make a visualization that combines violinplot and swarmplot.

When I make the violinplot only with the following:

sns.violinplot(data=driver_laps,
               x="Driver",
               y="LapTime(s)",
               order=finishing_order,
               inner="box",
               palette=driver_colors)

I get the following plot without issue:

However, when I try to make the swarmplot on top of the violinplot or by itself with the following:

sns.swarmplot(data=driver_laps,
              x="Driver",
              y="LapTime(s)"
              )

the following error is thrown:

Traceback (most recent call last):

The above exception was the direct cause of the following exception:

P.S Making the violinplot with inner="point" triggers the same error.

Caused by this library: timple

[McHouse]

I just ran into the same Casper-Guo problem.

Verified correct data just before calling sns.swarmplot
Apart from knowing that Timple may be to blame, any possible solution? Anything I can try to solve it?
