TypeError on page https://hvplot.holoviz.org/user_guide/Plotting.html

[SandervandenOord]

There's currently an error displayed for this code block on page https://hvplot.holoviz.org/user_guide/Plotting.html:

flight_subset = flights[flights.carrier.isin([b'AA', b'US', b'OH'])]
flight_subset.hvplot.hist('depdelay', by='carrier', bins=20, bin_range=(-20, 100), width=300, subplots=True)

TypeError: Object of type 'Array' is not JSON serializable
:NdLayout [carrier]
:Histogram [depdelay] (depdelay_count)

Thanks for reporting this error!

Definitely should be working so I'll file it as a bug and assign it to the next milestone.

After accidentally creating a duplicate of this issue in #583, I think I found the problem.
The issue seems to be the bytes objects in the carrier list, the example works with regular strings, so just change this line:

flight_subset = flights[flights.carrier.isin(['AA', 'US', 'OH'])]
