df = leaguelineupviz.LeagueLineupViz(date_from_nullable=date_from, date_to_nullable=date_to, season=season, measure_type_detailed_defense=measure_type, per_mode_detailed=per_mode, minutes_min=10).get_data_frames()[0]

When I print this data frame out, I only receive the statistics of the various lineups for the entire season, not just for my desired date range.

Here are the two formats for the date_from and date_to I have tried:
10/22/2019, OCT 22, 2019

I am assuming that I am formatting the dates wrong, can anyone help and let me know the proper way to format them?
